Dear all, I get an error due to the definition of the variable Ntrials, which as far as I understand, it is done in prepare_freq_matrices.m at lines 76 -> 85: ------------------------------------------------- % the time-frequency latency has already been squeezed away (see above) if strcmp(freq.dimord, 'chan_freq') Ntrials = 1; elseif strcmp(freq.dimord, 'rpt_chan_freq') Ntrials = length(freq.cumtapcnt); elseif strcmp(freq.dimord, 'rpttap_chan_freq') Ntrials = length(freq.cumtapcnt); else error('unrecognized dimord for frequency data'); end ------------------------------------------------- If the number of trials is less than the number of frequencies, Ntrials = length(freq.cumtapcnt) should be replaced by Ntrials = size(freq.cumtapcnt,1); Thanks a lot Andrea

svn commit -m "changed length() into size( ,1) to avoid crash when nrpt<nfreq: thanks to Andrea" prepare_freq_matrices.m Sending prepare_freq_matrices.m Transmitting file data . Committed revision 7451. @Andrea: could you test whether it works OK?
