freqanalysis_mtmconvol

[Jeroen Geuze]

Dear Fieltrip team,

I'm using freqanalysis_mtmconvol to extract single trial TFR data.
What I noticed when running the code is that not all my trials end up
in the 4D powspctrm field of the result struct. I have used two
datasets. One contains 193 trials and the other 324. When I run
freqanalysis, I am left with 154 and 140 trials respectively in the
rpt part of powspctrm. Is there a problem here or is my fieldtrip
ignorance playing up.
The config I used:

cfg              = [];
cfg.output       = 'pow';
cfg.channel      = 'all';
cfg.method       = 'mtmconvol';
cfg.taper        = 'hanning';
cfg.foi          = 5:1:40;
cfg.t_ftimwin    = 4./cfg.foi;  % 4 cycles per time window
cfg.toi          = -0.5:0.05:2;
cfg.keeptrials   = 'yes';

Thanks in advance for any help,


Jeroen Geuze
