When doing a FC analysis, there is no need to run mkcontrast. selxavg3-sess figures out that you are doing a FC analysis and creates the appropriate contrast. The name of the contrast automatically created will be the name of the FC passed to fcseed-config, eg, if you used
-fcname L_Posteriorcingulate.dat
then, the contrast would be called L_Posteriorcingulate, which can then be passed to other commands (eg, isxconcat-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
