uc-echo is used to analyse data from NGS-hardware (Next Generation 
Sequenzing). One advantage of such hardware is that it is able to analyse 
lots of short fragments in parallel and thus being much faster than older 
algorithms. Unfortunately the error rate in NGS-data is higher and thus 
more data is needed simultaneously to be able to correct this and to get a 
final result with high accuracy. As the ECHO algorithm does not need some 
reference data, the need for RAM is further increased.

I am not an NGS expert but I think that useful work can only be done 
with uc-echo when lots of RAM is available. But maybe others can comment 
on this ...
