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.

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 series of numbers (for every of the merged maps), however they don't change if I omit the roi part which leads me to believe that the average is calculated across the whole cortex and not specifically in areas I want to specify. What would be the best way to find out the mean myelination values in a specific roi (which is defined by the file with significantly different areas)? I hope you understand what I mean. Thanks a lot for your help!
