Hi everyone,
I was wondering if ft_sourceanalysis has an option to return Fourier coefficients when used to apply a filter to the output of ft_freqanalysis. The source average filter was obtained with eLORETA. My config parameters are below, and the output I get is power at every source, for every trial.
I am interested in getting the Fourier coefficients at source level to then be able to estimate connectivity (PLV) between sources.
Thank you,
Ina
cfg = [];
cfg.sourcemodel = lf_inside;
cfg.sourcemodel.filter = source_inside.avg.filter;
cfg.output = 'fourier';
cfg.keeptrials = 'yes';
cfg.rawtrial = 'yes';
source_NF_filt = ft_sourceanalysis(cfg, freqNF_FT);
