-\section{Motivation:} Single Molecule Real-Time (SMRT) sequencing technology and Oxford
-Nanopore technologies (ONT) produce reads over 10kbp in length, which have
-enabled high-quality genome assembly at an affordable cost.  However, at
-present, long reads have an error rate as high as 10--15\%.  Complex and
-computationally intensive pipelines are required to assemble such reads.
-
-\section{Results:} We present a new mapper, minimap, and a \emph{de novo}
-assembler, miniasm, for efficiently mapping and assembling SMRT and ONT reads
-without an error correction stage. They can often assemble a sequencing run of
-bacterial data into a single contig in a few minutes, and assemble 45-fold
-\emph{C. elegans} data in 9 minutes, orders of magnitude faster than the
-existing pipelines. We also introduce a pairwise read mapping format (PAF) and
-a graphical fragment assembly format (GFA), and demonstrate the
-interoperability between ours and current tools.

-\section{Introduction}
-
-High-throughput short-read sequencing technologies, such as Illumina, have
-empowered a variety of biological researches and clinical applications that
-would not be practical with the older Sanger sequencing. However, the short
-read length (typically a few hundred basepairs) has posed a great challenge to
-\emph{de novo} assembly as many repetitive sequences and segmental duplications
-are longer than the read length and can hardly be resolved by short reads even
-with paired-end data~\citep{Alkan:2011zr}. Although with increased read length
-and improved algorithms we are now able to produce much better short-read
-assemblies than a few years ago, the contiguity and completeness of the
-assemblies are still not as good as Sanger assemblies~\citep{Chaisson:2015wj}.
-
-The PacBio's SMRT technology were developed partly as an answer to the
-problem with short-read \emph{de novo} assembly. However, due to the high
-per-base error rate, around 15\%, these reads were only used as a complement to
-short reads initially~\citep{Bashir:2012gb,Ribeiro:2012bx,Koren:2012pt},
-until~\citet{Chin:2013qr} and~\citet{Koren:2013fc} demonstrated the feasibility
-of SMRT-only assembly. Since then, SMRT is becoming the preferred technology
-for finishing small genomes and producing high-quality Eukaryotic
-genomes~\citep{Berlin:2015xy}.
-
-Oxford Nanopore Technologies (ONT) has recently offered another long-read
-sequencing technology. Although the per-base error rate was high at the
-early access phase~\citep{Quick:2014uf}, the latest data quality has been
-greatly improved. \citet{Loman:2015xu} confirmed that we can achieve
-high-quality bacterial assembly with ONT data alone.
-
-Published long-read assembly pipelines all include four stages: (i) all-vs-all
-raw read mapping, (ii) raw read error correction, (iii) assembly of error
-corrected reads and (iv) contig consensus polish. Stage (iii) may involve
-all-vs-all read mapping again, but as the error rate is much reduced at this
-step, it is easier and faster than stage (i). Table~\ref{tab:tools} shows the tools used for
-each stage. Notably, our tool minimap is a raw read overlapper and miniasm is
-an assembler. We do not correct sequencing errors, but instead directly produce
-unpolished and uncorrected contig sequences from raw read overlaps. The idea of
-correction-free assembly was inspired by talks given by Gene Myers.
-Sikic et al (personal communication) are also independently exploring such an
-approach.

-
-As we can see from Table~\ref{tab:tools}, each stage can be achieved with multiple tools.
-Although we have successfully combined tools into different pipelines, we
-need to change or convert the input/output formats to make them work
-together. Another contribution of this article is the proposal of concise
-mapping and assembly formats, which will hopefully encourage modular design of
-assemblers and the associated tools.

-\section{Methods}
-
-\subsection{General notations}
-
-Let $\Sigma=\{\mathrm{A},\mathrm{C},\mathrm{G},\mathrm{T}\}$ be the
-alphabet of nucleotides. For a symbol $a\in\Sigma$, $\overline{a}$ is the
-Watson-Crick complement of $a$. A string $s=a_1a_2\cdots a_n$ over
-$\Sigma$ is also called a \emph{DNA sequence}. Its length is $|s|=n$;
-its \emph{reverse complement} is $\overline{s}=\overline{a_1a_2\cdots
-a_n}=\overline{a}_n\overline{a}_{n-1}\cdots\overline{a}_1$.
-For convenience, we define strand function
-$\pi:\Sigma^*\times\{0,1\}\to\Sigma^*$ such that $\pi(s,0)=s$ and
-$\pi(s,1)=\overline{s}$. Here $\Sigma^*$ is the set of all DNA sequences.
-
-By convention, we call a $k$-long DNA sequence as a \emph{$k$-mer}. We use the
-notation $s^k_i=a_i\cdots a_{i+k-1}$ to denote a $k$-long substring of $s$
-starting at $i$. $\Sigma^k$ is the set of all $k$-mers.
-
-\subsection{Minimap}
-
-\subsubsection{Overview of $k$-mer based sequence similarity search}\label{sec:minimapov}
-
-BLAST~\citep{Altschul:1997vn} and BLAT~\citep{Kent:2002jk} are among the most
-popular sequence similarity search tools. They use one $k$-mer hash function
-$\phi:\Sigma^k\to\mathbb{Z}$ to hash $k$-mers at the positions
-$1,w+1,2w+1,\ldots$ of a target sequence and keep the hash values in a hash
-table. Upon query, they use the same hash function on every $k$-mer of the
-query sequence and look up the hash table for potential matches. If there are
-one or multiple $k$-mer matches in a small window, these aligners extend the
-matches with dynamic programming to construct the final alignment.
-
-DALIGNER~\citep{DBLP:conf/wabi/Myers14} does not use a hash table. It instead
-identifies $k$-mer matches between two sets of reads by sorting $k$-mers and
-merging the sorted lists. DALIGNER is fast primarily because sorting and
-merging are highly cache efficient.
-
-MHAP~\citep{Berlin:2015xy} differs from others in the use of MinHash
-sketch~\citep{Broder:1997aa}.  Briefly, given a read sequence $s$ and $m$
-$k$-mer hash functions $\{\phi_j\}_{1\le j\le m}$, MHAP computes
-$h_j=\min\{\phi_j(s_i^k):1\le i\le |s|-k+1\}$ with each hash function $\phi_j$, and
-takes list $(h_j)_{1\le j\le m}$, which is called the \emph{sketch} of
-$s$, as a reduced representation of $s$. Suppose $(h_j)_j$ and $(h'_j)_j$ are
-the sketches of two reads, respectively. When the two reads are similar to each
-other or have significant overlaps, there are likely to exist multiple $j$ such
-that $h_j=h'_j$. Potential matches can thus be identified. A limitation of
-MinHash sketch is that it always selects a fixed number of hash values
-regardless of the length of the sequences. This may waste space or hurt
-sensitivity when input sequences vary greatly in lengths.
-
-Minimap is heavily influenced by all these works. It adopts the idea of sketch
-like MHAP but takes minimizers \citep{Roberts:2004fv} as a reduced
-representation instead; it stores $k$-mers in a hash table like BLAT and MHAP
-but also uses sorting extensively like DALIGNER. In addition, minimap is
-designed not only as a read overlapper but also as a read-to-genome and
-genome-to-genome mapper. It has more potential applications.

-\caption{Compute minimizers}\label{alg:minimizer}
-\end{algorithm}
-
-Loosely speaking, a $(w,k)$-minimizer of a string is the
-smallest $k$-mer in a surrounding window of $w$ consecutive $k$-mers. Formally,
-let $\phi:\Sigma^k\to\mathbb{Z}$ be a $k$-mer hash function.
-A \emph{double-strand $(w,k,\phi)$-minimizer}, or simply a \emph{minimizer}, of a
-string $s$, $|s|\ge w+k-1$, is a triple $(h,i,r)$ such that there exists
-$\max(1,i-w+1)\le j\le\min(i,|s|-w-k+1)$ which renders
-$$
-h=\phi(\pi(s_i^k,r))=\min\big\{\phi(\pi(s_{j+p}^k,r')):0\le p<w,r'\in\{0,1\}\big\}
-$$
-Let $\mathcal{M}(s)$ be the set of minimizers of $s$.  Algorithm~\ref{alg:minimizer} gives the
-pseudocode to compute $\mathcal{M}(s)$ in $O(w\cdot|s|)$ time.  Our actual
-implementation is close to $O(|s|)$ in average case. It uses a queue to cache
-the previous minimals and avoids the loops at line~1 and~2 most of time. In
-practice, time spent on collecting minimizers is insignificant.
-
-A natural choice of hash function $\phi$ is to let $\phi(\mathrm{A})=0$,
-$\phi(\mathrm{C})=1$, $\phi(\mathrm{G})=2$ and $\phi(\mathrm{T})=3$ and for a
-$k$-mer $s=a_1\cdots a_k$, define
-$$
-\phi(s)=\phi(a_1)\times4^{k-1}+\phi(a_2)\times4^{k-2}+\cdots+\phi(a_k)
-$$
-This hash function always maps a $k$-mer to a distinct $2k$-bit integer. A
-problem with this $\phi$ is that poly-A, which is often highly enriched in
-genomes, always gets zero, the smallest value. We may oversample these
-non-informative poly-A and hurt practical performance. To alleviate this issue,
-we use function $\phi'=h\circ\phi$ instead, where $h$ is an invertible integer
-hash function on $[0,4^k)$ (Algorithm~\ref{alg:invhash}; http://bit.ly/invihgi). The
-invertibility of $h$ is not essential, but as such $\phi'$ never maps two
-distinct $k$-mers to the same $2k$-bit integer, it helps to reduce hash
-collisions.

-\caption{Invertible integer hash function}\label{alg:invhash}
-\end{algorithm}
-
-Note that in a window of $w$ consecutive $k$-mers, there may be more than one
-minimizers. Algorithm~\ref{alg:minimizer} keeps them all with the loop at line~2. This way, a
-minimizer of $s$ always corresponds to a minimizer of $\overline{s}$.
-\citet{Roberts:2004fv} did not discuss the treatment of such equally good
-minimizers.
-
-For read overlapping, we use $k=15$ and $w=5$ to find minimizers.

-		\ForEach{$(h,i,r)\in \mathcal{M}$} {
-			$\mathcal{H}[h]\gets\mathcal{H}[h]\cup\{(t,i,r)\}$\;
-		}
-	}
-	\Return $\mathcal{H}$\;
-}
-\caption{Index target sequences}\label{alg:idx}
-\end{algorithm}
-
-Algorithm~\ref{alg:idx} describes indexing target sequences. It keeps minimizers of all target
-sequences in a hash table where the key is the minimizer hash and the value is
-a set of target sequence index, the position of the minimizer and the strand
-(packed into one 64-bit integer).
-
-In implementation, we do not directly insert minimizers to the hash table.
-Instead, we append minimizers to an array and sort the array after collecting
-all minimizers. The hash table keeps the intervals on the sorted array. This
-procedure dramatically reduces heap allocations and cache misses, and is
-supposedly faster than direct hash table insertion.

-Given two sequences $s$ and $s'$, we say we find a \emph{minimizer hit}
-$(h,x,i,i')$ if there exist $(h,i,r)\in\mathcal{M}(s)$ and
-$(h,i',r')\in\mathcal{M}(s')$ with $x=r\oplus r'$ ($\oplus$ is the XOR
-operator). Here $h$ is the minimizer hash value, $x$ indicates the relative
-strand and $i$ and $i'$ are the positions on the two sequences, respectively.
-We say two minimizer hits $(h_1,x,i_1,i'_1)$ and $(h_2,x,i_2,i'_2)$ are
-\emph{$\epsilon$-away} if 1) $x=0$ and $|(i_1-i'_1)-(i_2-i'_2)|<\epsilon$
-or 2) $x=1$ and $|(i_1+i'_1)-(i_2+i'_2)|<\epsilon$. Intuitively,
-$\epsilon$-away hits are approximately colinear within a band of width
-$\epsilon$ (500bp by default).  Given a set of minimizer hits $\{(h,x,i,i')\}$, we can cluster
-$i-i'$ for $x=0$ or $i+i'$ for $x=1$ to identify long colinear matches.
-This procedure is inspired by Hough Transformation mentioned
-by~\citet{sovic:2015aa}.

-\caption{Map a query sequence}\label{alg:map}
-\end{algorithm}
-
-Algorithm~\ref{alg:map} gives the details of the mapping algorithm. The loop at line~1
-collects minimizer hits between the query and all the target sequences. The
-loop at line~2 performs a single-linkage clustering to group approximately
-colinear hits. Some hits in a cluster may not be colinear because two minimizer
-hits within distance $\epsilon$ are always $\epsilon$-away. To fix this issue,
-we find the maximal colinear subset of hits by solving a longest increasing
-sequencing problem (line~3). This subset is the final mapping result. In
-practical implementation, we set thresholds on the size of the subset (4 by
-default) and the number of matching bases in the subset to filter poor mappings
-(100 for read overlapping).
-
-\subsection{Assembly graph}
-
-Two strings $v$ and $w$ may be mapped to each other based on their sequence
-similarity. If $v$ can be mapped to a substring of $w$, we say $w$
-\emph{contains} $v$. If a suffix of $v$ and a prefix of $w$ can be mapped to
-each other, we say $v$ \emph{overlaps} $w$, written as $v\to w$.
-If we regard strings $v$ and $w$ as vertices, the overlap relationship defines
-a directed edge between them. The \emph{length} of $v\to w$ equals the length
-of $v$'s prefix that does not overlap $w$.
-
-Let $G=(V,E,\ell)$ be a graph without multi-edges, where $V$ is a
-set of DNA sequences (vertices), $E$ a set of overlaps between them (edges) and
-$\ell:E\to\Re_+$ is the edge length function. $G$ is said to be
-\emph{Watson-Crick complete} if i) $\forall v\in V$, $\overline{v}\in V$ and
-ii) $\forall v\to w\in E$, $\overline{w}\to\overline{v}\in E$. $G$ is said to
-be \emph{containment-free} if any sequence $v$ is not contained in other
-sequences in $V$. If $G$ is both Watson-Crick complete and containment-free, it
-is an \emph{assembly graph}. By definition, any vertex $v$ has a
-\emph{complement vertex} $\overline{v}$ in the graph and any edge $v\to w$ has
-a \emph{complement edge} $\overline{w}\to\overline{v}$.  Let
-$\mathrm{deg}^+(v)$ be the indegree of $v$ and $\mathrm{deg}^-(v)$ be the
-outdegree. It follows that $\mathrm{deg}^-(v)=\mathrm{deg}^+(\overline{v})$.
-
-An assembly graph has the same topology as a string graph~\citep{Myers:2005bh},
-though the interpretation of the vertex set $V$ is different. In a string
-graph, $V$ is the set of the two ends of sequences, not the set of forward and
-reverse-complemented sequences. De Bruijn graph can be regarded as a special
-case of overlap graph. It is also an assembly graph.
-
-In an assembly graph, an edge $v\to w$ is \emph{transitive} if there exist
-$v\to u$ and $u\to w$. Removing a transitive edge does not affect the
-connectivity of the graph. A vertex $v$ is a \emph{tip} if ${\rm deg}^+(v)=0$
-and ${\rm deg}^-(v)>0$. The majority of tips are caused by artifacts or missing
-overlaps. A \emph{bubble} is a directed acyclic subgraph with a single source
-$v$ and a single sink $w$ having at least two paths between $v$ and $w$. The
-bubble is tight if ${\rm deg}^+(v)>1$ and ${\rm deg}^-(w)>1$. A bubble may be
-caused by variants between homologous haplotypes as well as missing overlaps.
-
-\subsection{Miniasm}
-
-\subsubsection{Trimming reads}
-
-Raw read sequences may contain artifacts such as untrimmed adapters and
-chimaera. The first step of assembly to reduce such artifacts by examining
-read-to-read mappings. For each read, miniasm finds the longest region that is
-covered by three or more good mappings (longer than 2000bp with at least 100bp
-non-redundant bases on matching minimizers) and trims bases outside the region.

-\caption{Bubble detection}\label{alg:popbub}
-\end{algorithm}
-
-After constructing the assembly graph, miniasm removes transitive
-edges~\citep{Myers:2005bh}, trims tips and pops small
-bubbles~\citep{Zerbino:2008uq}. Algorithm~\ref{alg:popbub} detects bubbles. It is
-adapted from Kahn's topological sorting algorithm~\citep{Kahn62aa}. It starts
-from the potential source and visits a vertex when all its incoming edges are
-visited before. Algorithm~6 only detects bubbles. We can keep track of the
-optimal parent vertex at line~1 and then backtrack to collapse bubbles to a
-single path. Fermi~\citep{Li:2012fk} uses a similar algorithm except that it
-keeps two optimal paths through the bubble.  \citet{DBLP:conf/wabi/OnoderaSS13}
-and \citet{TCS15} have also independently found similar algorithms.
-
-In addition, if $v\to w_1$ and $v\to w_2$ exist and $\ell(v\to w_1)<\ell(v\to
-w_2)$, miniasm removes $v\to w_2$ if $[|v|-\ell(v\to w_2)]/[|v|-\ell(v\to
-w_1)]$ is small enough (70\% by default). When there are longer overlaps,
-shorter overlaps after transitive reduction may be due to repeats.
-However, non-repetitive overlaps may also be removed at a small chance, which
-leads to missing overlaps and misassemblies.
-
-\subsubsection{Generating unitig sequences}
-
-If there are no multi-edges in the assembly graph, we can use $v_1\to
-v_2\to\cdots\to v_k$ to represent a path consisting of $k$ vertices. The
-sequence spelled from this path is the concatenation of vertex substrings:
-$v_1[1,\ell(v_1\to v_2)]\circ v_2[1,\ell(v_2\to v_3)]\circ\cdots\circ
-v_{k-1}[1,\ell(v_{k-1},v_k)]\circ v_k$, where $v[i,j]$ is the substring between
-$i$ and $j$ inclusive, and $\circ$ is the string concatenation operator.
-
-In a transitively reduced graph, a \emph{unitig} is a path $v_1\to
-v_2\to\cdots\to v_k$ such that ${\rm deg}^+(v_i)={\rm deg}^-(v_{i+1})=1$ and i)
-$v_1=v_k$ or ii) ${\rm deg}^-(v_1)\not=1$ and ${\rm deg}^-(v_k)\not=1$.
-Its sequence is the sequence spelled from the path. Intuitively, a unitig is a
-maximal path on which adjacent vertices can be ``unambiguously merged'' without
-affecting the connectivity of the original assembly graph.
-
-As miniasm does not correct sequencing errors, the error rate of unitig
-sequence is the same as the error rate of the raw input reads. It is in theory
-possible to derive a better unitig sequence by taking the advantage of read
-overlaps. We have not implemented such a consensus tool yet.

-\end{tabular}
-}{PAF is TAB-delimited text format with each line consisting of the above fixed
-fields. When the alignment is available, column 11 equals the total number of

-available, column 10 and 11 can be approximate. PAF may optionally have
-additional fields in the SAM-like typed key-value format~\citep{Li:2009ys}.}
-\end{table}
-
-PAF is a lightweight format keeping the key mapping information (Table~\ref{tab:paf}).
-Minimap outputs mappings in PAF, which are taken by miniasm as input for

-}{GFA is a line-based TAB-delimited format. Each line starts with a single
-letter determining the interpretation of the following TAB-delimited fields. In
-GFA, segment refers to a read or a unitig. A line start with `S' gives the name
-and sequence of a segment. When the sequence is not available, it can be a star
-`*'. Overlaps between segments are represented in lines starting with `L',
-giving the names and orientations of the two segments in an overlap. The last
-field `CIGAR' on an `L'-line describes the detailed alignment of the overlap if
-available. In addition to the types of lines in the table, GFA may contain
-other line types starting with different letters. Each line may optionally have
-additional SAM-like typed key-value pairs.}
-\end{table}
-
-GFA is a concise assembly format (Table~\ref{tab:gfa}; http://bit.ly/gfaspec) initially proposed by
-us prior to miniasm and later improved by community (P. Melsted, S.  Jackman,
-J. Simpson and E. Garrison, personal communication). GFA has an explicit
-relationship to an assembly graph -- an `S' line in the GFA corresponds to a
-vertex and its complement in the graph; an `L' line corresponds to an edge and
-its complement. GFA is able to represent graphs produced at all the stages of
-an assembly pipeline, from initial read overlaps to the unitig relationship in
-the final assembly.
-
-FASTG (http://bit.ly/fastgfmt) is another assembly format prior to GFA.
-It uses different terminologies. A vertex in an assembly graph is called an
-edge in FASTG, and an edge is called an adjacency. In FASTG, subgraphs can be
-nested, though no tools work with nested graphs due to technical complications.
-In addition, with nesting, one assembly graph can be represented in distinct
-ways, which we regard as a limitation of FASTG.

-\section{Results}
-
-\subsection{Assembling bacterial genomes}
-
-We evaluated the performance of miniasm on 17 bacterial data sets
-(Table~\ref{tab:data}) with command line `minimap -Sw5 -L100 -m0 reads.fa reads.fa $|$
-miniasm -f reads.fa -'. Miniasm is able to derive a single contig per
-chromosome/plasmid for all but four data sets: 3 extra $>$50kb contigs for
-ERS554120, and 1 extra contig for ERS605484, PBcR-ONT-ec and MAP-006-pcr-1
-each. 
-
-Encouraged by the single-contig assembly for PBcR-PB-ec at only 30-fold
-coverage, we randomly down-sampled PacBio data sets and tried to assemble the
-subset. For PB-ecoli, miniasm still produced a single contig at 24-fold
-coverage, or two contigs at 20-fold. For the other data sets, however, miniasm
-generated fragmented assemblies when we sampled a third of reads. We speculate
-the shorter read lengths of the ERS* data sets made it more difficult to
-produce good assemblies at relatively low coverage.
-
-We have also run the PBcR pipeline~\citep{Berlin:2015xy}. PBcR requires a spec
-file. We took `pacbio.spec' from the PBcR-PB-ec example and `oxford.spec' from
-PBcR-ONT-ec, and applied them to all data sets based on their data types. MAP*
-data sets only provide FASTA sequences for download. We assigned quality 9 to
-all bases as PBcR requires base quality. PBcR assembled all PacBio data sets
-without extra contigs longer than 50kb -- better than miniasm. However, on the
-ONT data sets, PBcR produced more fragmented assemblies for MAP-006-2,
-MAP-006-pcr-1 and MAP-006-pcr-2, and deleted a 300kb region for the PBcR-ONT-ec
-data set. 
-
-With four CPU cores, it took miniasm 14 seconds to assemble the 30-fold
-PBcR-PB-ec data set and 2 minutes to assemble the 160-fold PB-ecoli data set.
-PBcR, with four CPU cores, too, is about 700 times slower on PBcR-PB-ecoli and
-60 times slower on PB-ecoli.  It is slower on low-coverage data
-because PBcR automatically switches to the slower sensitive mode. Here we
-should remind readers that without an error correction stage, the contig
-sequences generated by miniasm are of much lower accuracy in comparison to
-PBcR. The speed comparison is not fair. Nonetheless, miniasm is still tens of
-times faster than PBcR excluding the time spent on error correction.
-
-\subsection{Assembling a C. elegans genome}
-
-\begin{figure}[tb]
-\includegraphics[width=.48\textwidth]{ce}
-\caption{Dotter plot comparing the miniasm assembly and the {\it C. elegans}
-reference genome. Thin gray lines mark the contig or chromosome boundaries. The
-three arrows indicate large-scale misassemblies visible from the
-plot. The mapping is done with `minimap -L500'.}\label{fig:ce}
-\end{figure}
-
-We assembled a 45-fold {\it C. elegans} data set (Table~\ref{tab:data}). With 16 CPU cores,
-miniasm assembled the data in 9 minutes, achieving an N50 size 2.8Mb. From the
-dotter plot (Figure~\ref{fig:ce}), we observed three large-scale misassemblies
-(readers are advised to zoom into the vector graph to see the details).  Due to
-the high per-base error rate of the miniasm contigs, we have not been able to
-produce realible whole-genome alignment to analyze local misassemblies in a
-satisfactory manner.
-
-PacBio has assembled the same data set with HGAP3~\citep{Chin:2013qr}. HGAP3
-produces shorter contigs (N50=1.6Mb), but does not incur large-scale
-misassemblies visible from the dotter plot between the {\it C. elegans}
-reference genome and the contigs.
-
-We have also tried PBcR on this data set. Based on the intermediate progress
-report, we estimated that with 16 CPU cores, it would take a week or so to
-finish the assembly in the automatically chosen `sensitive' mode.
-
-\subsection{Switching read overlappers}
-
-Miniasm also works with other overlappers when we convert their output format
-to PAF. On the 30-fold PBcR-PB-ec data set, we are able to produce a single
-contig with DALIGNER (option -k15 -h50), MHAP (option
-\mbox{--pacbio-sensitive}) and GraphMap (option -w owler). DALIGNER is the
-fastest, taking 65 seconds with four CPUs.  Minimap is five times as fast on
-this data set and is 18 times as fast on PB-ecoli at 160-fold. Minimap is
-faster on larger data sets possibly because without staging all possible hits
-in RAM, minimap is able to process more reads in a batch while a large batch
-usually helps performance. We should note that DALIGNER generates alignments
-while minimap does not. Minimap would possibly be slower if it included an
-alignment step. In this regard, the performance of DALIGNER is very impressive.

-\section{Discussions}
-
-Miniasm confirms long noisy reads can be assembled without
-an error correction stage, and without this stage, the assembly process can be
-greatly accelerated and simplified, while achieving comparable contiguity and
-large-scale accuracy to existing pipelines, at least for genomes without
-excessive repetitive sequences. If we can develop a fast tool to generate
-high-quality contig sequences which miniasm currently lacks, we may be able to
-dramatically speed up the entire assembly pipeline. MinION allows
-users to pause sequencing and reload samples. Fast assembly will not only
-alleviate the computational burden, but also help us to decide if enough data
-have been collected.
-
-Our main concern with miniasm is that when we look at a low-identity match
-between two noisy reads, it is difficult to tell whether the low identity is
-caused by the stochastically higher base error rate on reads, or because
-reads come from two recent segmental duplications.
-In comparison, error correction takes the advantage of multiple reads and in
-theory has more power to distinguish high error rate from duplications/repeats.
-Bacteria and {\it C. elegans} evaluated in this article are repeat sparse.
-We are yet to know the performance of miniasm given repeat-rich genomes.  In addition, miniasm has
-not been optimized for large repeat-rich genomes. It reads all hits into RAM,
-which may not be practical when there are too many. We need to filter
-repetitive hits, introduce disk-based algorithms (e.g. for sorting) or stream
-hits before removing contained reads. Working with large complex genomes will
-be an important future direction.
-
-Minimap is primarily used as a read overlapper in this article. It in fact has a
-wider range of applications in addition to overlapping.  For example, with four
-CPU cores, it is able to map 1.6Gb PacBio reads to the human genome in 2.5
-minutes, map 1Gb {\it E. coli} reads to pre-indexed 9.6Gb bacterial genome in 3
-minutes and to pre-indexed 100Gb nt database in an hour with a third of time
-spent on loading the index from the network file system. It can also map 2800
-bacterial genomes to themselves in an hour. Minimap is fast, but is not as
-sensitive as proper whole-genome aligners and recent long-read aligners such as
-LASTZ~\citep{harris:2007aa}, LAST~\citep{Kiebasa:2011aa} and GraphMap. They use
-shorter spaced seeds which greatly help sensitivity at the cost of performance.
-
-Oxford Nanopore is working on PromethIon and PacBio will deliver PacBio Sequel
-next year. Both sequencers promise significantly reduced sequencing cost and
-increased throughput, which may stimulate the adoption of long-read sequencing
-and subsequently the development of long-read mappers and assemblers. We hope
-in this process, the community could standardize the input and output formats
-of various tools, so that a developer could focus on a component he or she
-understands best. Such a modular approach has been proved to be fruitful in the
-development of short-read tools -- in fact, the best short-read pipelines all
-consist of components developed by different groups -- and will be equally
-beneficial to the future development of long-read mappers and assemblers.

- % This is an author-year citation style bibliography. As such, it is
- % non-standard LaTeX, and requires a special package file to function properly.
- % Such a package is    natbib.sty   by Patrick W. Daly
- % The form of the \bibitem entries is
- %   \bibitem[Jones et al.(1990)]{key}...
- %   \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
- % The essential feature is that the label (the part in brackets) consists
- % of the author names, as they should appear in the citation, with the year
- % in parentheses following. There must be no space before the opening
- % parenthesis!
- % With natbib v5.3, a full list of authors may also follow the year.
- % In natbib.sty, it is possible to define the type of enclosures that is
- % really wanted (brackets or parentheses), but in either case, there must
- % be parentheses in the label.
- % The \cite command functions as follows:
- %   \cite{key} ==>>                Jones et al. (1990)
- %   \cite[]{key} ==>>              (Jones et al., 1990)
- %   \cite[chap. 2]{key} ==>>       (Jones et al., 1990, chap. 2)
- %   \cite[e.g.][]{key} ==>>        (e.g. Jones et al., 1990)
- %   \cite[e.g.][p. 32]{key} ==>>   (e.g. Jones et al., p. 32)
- %   \citeauthor{key}               Jones et al.

-\ProvidesPackage{natbib}
-        [2000/07/24 7.0a (PWD)]
- % This package reimplements the LaTeX \cite command to be used for various
- % citation styles, both author-year and numerical. It accepts BibTeX
- % output intended for many other packages, and therefore acts as a
- % general, all-purpose citation-style interface.
- %
- % With standard numerical .bst files, only numerical citations are
- % possible. With an author-year .bst file, both numerical and
- % author-year citations are possible.
- %
- % If author-year citations are selected, \bibitem must have one of the
- %   following forms:
- %   \bibitem[Jones et al.(1990)]{key}...
- %   \bibitem[Jones et al.(1990)Jones, Baker, and Williams]{key}...
- %   \bibitem[Jones et al., 1990]{key}...
- %   \bibitem[\protect\citeauthoryear{Jones, Baker, and Williams}{Jones
- %       et al.}{1990}]{key}...
- %   \bibitem[\protect\citeauthoryear{Jones et al.}{1990}]{key}...
- %   \bibitem[\protect\astroncite{Jones et al.}{1990}]{key}...
- %   \bibitem[\protect\citename{Jones et al., }1990]{key}...
- %   \harvarditem[Jones et al.]{Jones, Baker, and Williams}{1990}{key}...
- %
- % This is either to be made up manually, or to be generated by an
- % appropriate .bst file with BibTeX.
- %                            Author-year mode     ||   Numerical mode
- % Then, \citet{key}  ==>>  Jones et al. (1990)    ||   Jones et al. [21]
- %       \citep{key}  ==>> (Jones et al., 1990)    ||   [21]
- % Multiple citations as normal:
- % \citep{key1,key2}  ==>> (Jones et al., 1990; Smith, 1989) || [21,24]
- %                           or  (Jones et al., 1990, 1991)  || [21,24]
- %                           or  (Jones et al., 1990a,b)     || [21,24]
- % \cite{key} is the equivalent of \citet{key} in author-year mode
- %                         and  of \citep{key} in numerical mode
- % Full author lists may be forced with \citet* or \citep*, e.g.
- %       \citep*{key}      ==>> (Jones, Baker, and Williams, 1990)
- % Optional notes as:
- %   \citep[chap. 2]{key}    ==>> (Jones et al., 1990, chap. 2)
- %   \citep[e.g.,][]{key}    ==>> (e.g., Jones et al., 1990)
- %   \citep[see][pg. 34]{key}==>> (see Jones et al., 1990, pg. 34)
- %  (Note: in standard LaTeX, only one note is allowed, after the ref.
- %   Here, one note is like the standard, two make pre- and post-notes.)
- %   \citealt{key}          ==>> Jones et al. 1990
- %   \citealt*{key}         ==>> Jones, Baker, and Williams 1990
- %   \citealp{key}          ==>> Jones et al., 1990
- %   \citealp*{key}         ==>> Jones, Baker, and Williams, 1990
- % Additional citation possibilities (both author-year and numerical modes)
- %   \citeauthor{key}       ==>> Jones et al.

- % Defining the citation style of a given bib style:
- % Use \bibpunct (in the preamble only) with 6 mandatory arguments:
- %    1. opening bracket for citation
- %    2. closing bracket
- %    3. citation separator (for multiple citations in one \cite)
- %    4. the letter n for numerical styles, s for superscripts
- %        else anything for author-year
- %    5. punctuation between authors and date
- %    6. punctuation between years (or numbers) when common authors missing
- % One optional argument is the character coming before post-notes. It
- %   appears in square braces before all other arguments. May be left off.
- % Example (and default) \bibpunct[, ]{(}{)}{;}{a}{,}{,}
- %
- % To make this automatic for a given bib style, named newbib, say, make
- % a local configuration file, natbib.cfg, with the definition
- %   \newcommand{\bibstyle at newbib}{\bibpunct...}
- % Then the \bibliographystyle{newbib} will cause \bibstyle at newbib to
- % be called on THE NEXT LATEX RUN (via the aux file).
- %
- % Such preprogrammed definitions may be invoked in the text (preamble only)
- %  by calling \citestyle{newbib}. This is only useful if the style specified
- %  differs from that in \bibliographystyle.
- %
- % With \citeindextrue and \citeindexfalse, one can control whether the
- % \cite commands make an automatic entry of the citation in the .idx
- % indexing file. For this, \makeindex must also be given in the preamble.
- %
- % LaTeX2e Options: (for selecting punctuation)
- %   round  -  round parentheses are used (default)
- %   square -  square brackets are used   [option]
- %   curly  -  curly braces are used      {option}
- %   angle  -  angle brackets are used    <option>
- %   colon  -  multiple citations separated by colon (default)
- %   comma  -  separated by comma
- %   authoryear - selects author-year citations (default)
- %   numbers-  selects numerical citations
- %   super  -  numerical citations as superscripts
- %   sort   -  sorts multiple citations according to order in ref. list
- %   sort&compress   -  like sort, but also compresses numerical citations
- %   longnamesfirst  -  makes first citation full author list
- %   sectionbib - puts bibliography in a \section* instead of \chapter*
- % Punctuation so selected dominates over any predefined ones.
- % LaTeX2e options are called as, e.g.
- %        \usepackage[square,comma]{natbib}
- % LaTeX the source file natbib.dtx to obtain more details
- % or the file natnotes.tex for a brief reference sheet.
