Re: [HCP-Users] Extraction of mean myelination values from a custom roi

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

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. Peace, Matt. From:

Dear Matt, Thanks for the references and answers. Given your experience would you consider the short spike that I mentioned as noise or this is not so clear cut? Many thanks, Romuald On Mon, Oct 16, 2017 at 8:54 PM, Glasser, Matthew wrote: > >1. ICA+FIX removes the

[HCP-Users] Extraction of mean myelination values from a custom roi

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
