<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">Dear list,
<br>
<br>
after installing the newest version of Fieldtrip today, I have encountered a rather strange error . I am tying to compute corticomuscular coherence for an EEG/EMG dataset and it worked well so far. With the new version however, I get a reshape error I find
fard to understand. This is the code:<br>
<br>
cfg = [];<br>
cfg.frequency = 20;;<br>
cfg.grid = leadfield;<br>
cfg.method = 'dics';<br>
cfg.refchan = 'ExtR1';<br>
cfg.channel = {'EEG' 'ExtR1'};<br>
cfg.vol = hdm;<br>
cfg.dics.projectnoise = 'no';<br>
cfg.dics.lambda = '1%';<br>
cfg.dics.keepfilter = 'yes';<br>
cfg.dics.keeptrials = 'yes';<br>
cfg.dics.realfilter = 'yes';<br>
sourceAll = ft_sourceanalysis(cfg, freqAll); <br>
<br>
but this hasn't changed. The error pops up at lines 619/620 of ft_sourceanalysis (Cf = reshape(sum(Cf, 1) / Ntrials, [Nchans Nchans]);), where it supposedly just averages the CSD matrix over trials. And it makes kind of sense as the line says to reshape the
CSDs from a 1xNchans matrix into a [Nchans Nchans] one. But why is it poppin up now as nothing has changed in my analyses? I have checked the updates of the last months and I couldn't find anything related to this. So has any one an idea why the analysis crashes
at this point. <br>
<br>
Thanks in advance<br>
Best,<br>
David<br>
