[Freesurfer] mri_surfcluster

Dear Freesurfers,

I ran a comparison between different groups using mri_glmfit. Now I would like to correct the results in sig.mgh by multiple comparisons using FDR. I tried using tksurfer but it doesn't work so well on my computer and I read that freeview does not allow to do that yet.

I'm now trying to use mri_surfcluster to do it. Is this correct? mri_surfcluster --in sig.mgh --subject fsaverage --surf inflated --hemi lh --fdr 0.05 --sign pos

After I run it some thresholds appear in the terminal. Should I use these thresholds to create a FDR corrected sig.mgh map or is there a direct way of getting this using mri_surfcluster or other command?

Thank you so much!
