[FieldTrip] Issue with ft_freqanalysis

[Karen Konkoly]

Hi!

I am trying to run the following time frequency analysis:

starttime = 171.211000000000

endtime = 174.211000000000



cfg = [];

cfg.method = 'mtmconvol';

cfg.foi = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
25 26 27 28 29]

cfg.toi = [starttime:.1:endtime]

cfg.t_ftimwin = [.5 .5 .5 .5 .5 .5 .5 .5 .5 .5 .5 .5 .5 .5 .5 .5 .5 .5 .5
.5 .5 .5 .5 .5 .5 .5 .5 .5 .5]



freq = ft_freqanalysis(cfg, EEGdat);



It starts running, but then I get many errors:

Reference to non-existent field 'dimord'.

Error in dimlength (line 74)
      elseif strcmp(data.(fld), 'rpt_pos')

Error in fixsampleinfo (line 57)
  ntrial = dimlength(data, 'rpt');

Error in ft_datatype_timelock (line 152)
      timelock = fixsampleinfo(timelock);

Error in ft_checkdata (line 269)
  data = ft_datatype_timelock(data, 'hassampleinfo', hassampleinfo);

Error in ft_freqanalysis (line 212)
data = ft_checkdata(data, 'datatype', {'raw', 'raw+comp', 'mvar'},
'feedback',
cfg.feedback, 'hassampleinfo', 'yes');


I am still making sure I have FieldTrip installed properly (after following
the instructions, the "eeglab2fieldtrip" function did not work unless I
added the subdirectory it was in to my matlab path manually, which I know
Fieldtrip is supposed to do automatically).


Any advice on how to overcome these errors?


Best,
Karen
