You can do this with Connectome Workbench command (wb_command -surface-layer and wb_command -volume-to-surface-mapping).

Subject: [Freesurfer] equivolumetric surfaces
External Email - Use Caution
Dear freesurfer experts,
I want to create an equivolumetric surfaces (using the tool from:
MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://github.com/kwagstyl/surface_tools) and to sample the intensities of the T1wDividedByT2w volume at all the depths.
I created the surfaces and after running the mri_vol2surf command I faced the error below. I don’t know why the path to the surface is not correct. I tried it in different devices with different versions of freesurfer but the results were the same. Any idea
what I did wrong? Thanks
