freqanalysis_wltconvol variance

[Ingrid Nieuwenhuis]

Dear Amr,



If you do freqanalysis with cfg.keeptrials = 'yes', you get the power per
trial. If you subsequently use freqdescriptives (see help for detailed
options) you can compute the variance over trials.

Hello,

I am expecting that you are averaging the power spectrum across the trials
in freqanalysis_wltconvol. Is there a way to compute the variance across the
number of trials?

Thanks in advance
