<p style="margin-top:0; margin-bottom:0">Dear users</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">I have an fMRI dataset comprising 113 volumes (from a single run). I would like to map information about events during the fMRI run - experimental condition and onset time - to the dataset. The events structure is stored
in a .txt file with four columns: run#, experimental condition, unique stimulus, and onset time. It looks something like this</p>

<div><br>
</div>
<div>I've tried to map this info to the fMRI dataset in the following way:</div>
<div><br>
</div>
<div><span style="font-family:Consolas,Courier,monospace">bold_fname = 'path_to_fMRI_dataset'</span><br>
</div>
<div>
<div><span style="font-family:Consolas,Courier,monospace">exp_data = pd.read_csv("path_to_txt", delimiter='\t', header = None)</span></div>
<div><span style="font-family:Consolas,Courier,monospace"></span><span style="font-family:Consolas,Courier,monospace">exp_data.columns = ['run','condition</span><span style="font-family:Consolas,Courier,monospace">','word','onset']</span><br>
<br>
<span style="font-family:Consolas,Courier,monospace">ds = fmri_dataset(bold_fname, targets = None)</span><br>
<span style="font-family:Consolas,Courier,monospace">ds.sa.time_coords = exp_data.onset</span></div>
<div><span style="font-family:Consolas,Courier,monospace">ds.sa.targets = exp_data.condition<br>
</span></div>
<br>
</div>
<p style="margin-top:0; margin-bottom:0">The problem with this is that there are more fMRI volumes than rows in the conditions.txt fie, hence I get the following error:</p>
<p style="margin-top:0; margin-bottom:0"></p>
<pre><span style="font-family:Consolas,Courier,monospace">Name: onset, dtype: float64` (Value length [45] does not match the required length [113] of attribute 'time_coords'.)</span></pre>
Can anyone suggest a workaround? Thanks in advance for any advice!<br>
