The -cifti-parcellate command is currently the easier way to do this, if
your ROIs don't overlap. The -roi option to -cifti-stats currently uses
only the first map, and only tests for whether the value is greater than 0,
so probably the first map in your roi input is actually all positive. Also
n
It might only be using the first ROI. Tim will know better what is the issue.
You might try converting the ROIs to a parcellation and then parcellating the
myelin map and converting the parcellated file to text or whatever you need.

Maybe if you post a picture I will know better what you were describing, as
what I said below is general.

Dear experts,
I have a question about extracting average myelination value from a custom
roi. What I did was the following:
wb_command -cifti-stats merged_myelin_maps_group1.dscalar.nii -reduce -MEAN
-roi
file_with_significant_differences_between_the_groups_thresholded_at_1.3.dscalar.nii
I get a
