If your index is in fsaverage space, then you can just concatenate the data together with

mri_concat subj1/data-in-fsaverage.nii.gz subj2/data-in-fsaverage.nii.gz ... --o stack.nii.gz

then just input stack.nii.gz into mri_glmfit, etc

Dear experts,

I have preprocessed my functional data using FSFAST. I have calculated an index for each of my ROIs' vertices in matlab, and then created a map for each hemisphere and subcortical regions using MRIwrite. I want to perform group analysis on these maps. I also want to apply cluster-wise multiple comparison correction. Since I have not defined an analysis using mkanalysis-sess, I do not know how to use isxconcat-sess and mri_glmfit. How should I perform this analysis?

Bests, Ladan
