Hello Freesurfer experts!
I see that there is a longitudinal processing pipeline for volume/cortical thickness. I was wondering if the same pipleline could be used for resting state functional connectivity based analysis?
Best,
Tracy
You can use the longitudinal anatomical analysis to inform the functional analysis across time, but there is not a longitudinal functional analysis per se.

Thanks Doug,
Is there a way to do a pairwise t-test of whole brain resting state connectivity? I have pre-intervention scans and post-intervention scans and want to compare pre vs post.
Best,
Tracy

Yes, run isxconcat-sess for the pre and the post separately. You will get two different stacks. Then run fscalc pre.nii.gz sub post.nii.gz -o pre-post.nii.gz Then use pre-post.nii.gz as input to mri_glmfit You can compute percent change instead as
fscalc pre.nii.gz pctdiff0 post.nii.gz -o pre-post.percent.nii.gz
