Hi list, I have two queries, please.
I'd like to have the z-score from my rsfMRI data (seed-analyis).
- I have extract the z-score from the Vtx Max
In details, after groups comparison analysis, I have opened the cache.th13.pos.sig.cluster.summary contained in group.diff folder and I have read the Vtx Max coordinates. Next, I have open the z.nii.gz of each subject and I have expected the z-score from the vertex which have the Vtx Max coordinates.
Is this procedure corrected?
Yes
- z-score of each subject from a common cluster
I would like to use the cluster which shows the group difference (cache.th13.pos.sig.cluster.nii.gz) as ROI mask. Thus, I would extract from it the average of the z-score which is contained in each subject. How should I do?
Use mri_segstats passing the z map as the input (--i) and the cluster map as the seg. The output will be --sum. Run with --help for more info
Thanks.
