[FieldTrip] ft_sourceanalysis, reshape error

[David Pedrosa]

Dear list,

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:

    cfg              = [];
    cfg.frequency    = 20;;
    cfg.grid        = leadfield;
    cfg.method       = 'dics';
    cfg.refchan      = 'ExtR1';
    cfg.channel         = {'EEG' 'ExtR1'};
    cfg.vol          = hdm;
    cfg.dics.projectnoise = 'no';
    cfg.dics.lambda       = '1%';
    cfg.dics.keepfilter   = 'yes';
    cfg.dics.keeptrials   = 'yes';
    cfg.dics.realfilter   = 'yes';
    sourceAll = ft_sourceanalysis(cfg, freqAll);

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.

Thanks in advance
Best,
David
