Surface coordinate of ROI

Dear MRtrix community,

Is there any way to find the surface coordinate of ROI we have created/imported in MRtrix ?


Hi Parand,

The question is slightly ambiguous. We don’t yet have the capability to use surface-based ROIs, so there’s no way to export the locations of those vertices that are included in the mask (for voxel-based ROIs, maskdump provides voxel locations). If you do in fact have surface-based data, I think your problem is missing an internal projection between voxel and surface data representations, which would need the use of tools outside of MRtrix3.
