Generate surrogate data error

Hi @Samiee

Thanks for the clarification on surrogate tPAC.

I am still facing two issue.

  1. I am unable to extract comodulogram from the tPAC full matrix.
    Even for an individual subject. Here's the error I get -
    I add the tPAC: ROI (Full) matrix in process 1.

** Error: [process_pac_comod] Frequency > Time-resolved Phase-Amplitude Coupling > Extracting comodulogram from tPAC maps
** Line 405: Index exceeds the number of array elements (0).

** Call stack:

  1. I am also unable to average the tPAC maps to generate one representative comodulogram per group.
    I add all the tPAC: ROI (Full) in process 1 -> Basic analysis of tPAC maps -> mean (over sources).
    But this is producing a mean file per participant, rather than one for an entire group.

Thanks for your help.
