Hi everybody,
I'm trying to compute coherence analyses following the coherence tutorial at http://www.fieldtriptoolbox.org/tutorial/coherence.
Since a couple of days, I have this error message in computing ft_freqanalysis:
Error using load
Unable to read file precompute_dpss: No such file or directory.
Error in dpss (line 9)
load precompute_dpss
Error in ft_specest_mtmfft>double_dpss (line 335)
tap = dpss(double(a), double(b), varargin{:});
Error in ft_specest_mtmfft (line 151)
tap =
double_dpss(ndatsample,ndatsample*(tapsmofrq./fsample))';
Error in ft_freqanalysis (line 494)
[spectrum,ntaper,foi] = ft_specest_mtmfft(dat, time, 'taper',
cfg.taper, options{:}, 'feedback', fbopt);
Is that a bug?
Here is the code I'm using:
cfg = [];
cfg.output = 'powandcsd';
cfg.method = 'mtmfft';
cfg.foilim = [5 40];
cfg.tapsmofrq = 5;
cfg.keeptrials = 'yes';
freq = ft_freqanalysis(cfg, eeg);
Thank you in advance,
Federica
