Dear all,
I keep thinking that I have done it, in that I think that I have recreated all the information that should be needed in a field trip TF object. I did this by bringing in the extra information from D.fttimelock, and creating the cfg field as if I had run it through FT_FREQANALYSIS. The structure has these fields:
l5d19 =
fsample: 250.0000
label: {68x1 cell}
trial: {[68x73 single]}
time: {[1x376 double]}
trialinfo: 1
cfg: [1x1 struct]
powspctrm: [68x73x376 single]
freq: [1x73 double]
dimord: 'chan_freq_time'
However, when I try and use my file in 'FT_FREQGRANDAVERAGE' , it does not recognise this as a TF object, and produces this error message:
??? Error using ==> ft_checkdata at 324
This function requires freq data as input.
Error in ==> ft_freqgrandaverage at 66
varargin{i} = ft_checkdata(varargin{i}, 'datatype', 'freq', 'feedback', 'no');
What is it that I am missing??
Best,
Duncan
