Hi list,
I have two queries, please.
I'd like to have the z-score from my rsfMRI data
(seed-analyis).
1) 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
2) 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
