The easiest thing is to just run mri_preproc on the baseline scans to
create a baseline stack. Then pass the baseline stack to the
mri_segstats command below with --i

Dear Freesurfer Experts,
I ran a longitudinal Cth analysis and found a cluster with significant
spc differences between two groups. It was easy to obtain the mean spc
values in that cluster for all the subjects. However,
I would also like to have a spreedsheet with the baseline mean Cth
values in that cluster for all my subjects to correlate with other
clinical measures.
My attempt was:
mri_segstats --i SPC_ANALYSIS_FOLDER/y.mgh --seg
SPC_ANALYSIS_FOLDER/SUBANALYSIS/mc-z.abs.th13.sig.cluster.mgh
--excludeid 0 --sum CTH_inSPC_cluster.sum
But obviously this is not the correct way to obtain for each subject
the mean Cth value in that cluster.
Any help would be much appreciated!
Thanks a lot in advance,
Fred
