[Freesurfer] seed-based functional connectivity: mkcontrast-sess

Dear FreeSurfer community,

I was wondering what my contrast-matrix should look like when doing a first-level analyses since there is no task involved. I tried looking at the -help flag, but I can’t see any options for setting a matrix without entering the numb of conditions.

This was the command I tried to use:

mkcontrast-sess -rmprestim -analysis restingstate.sm05.lh -contrast restingstate.lh

I’m sure I’m missing something here, but I can’t figure out what to do.

Thanks for the already given support!!

Best regards,

Robby
