Dea FreeSurfer experts,
I’m writing in order to ask how to map on a surface data from a volumetric MTR image.
I have volumetric Magnetization Transfer Ratio data co-registered to the subject native space of a subject (as produced by recon-all on a T1 acquisition). The subject, for which I have also the T1 and T2 scans, has been already processed with recon-all, then I have the complete folder of the subject, as produced by the recon-all standard pipeline.
I need a surface in the native subject space containing the MTR data, averaged along the surface normals for a certain amount of millimeters. It would also be useful to define the surface as in a certain midway between the pial and the white surfaces.
I tried to understand the mri_vol2surf tool but I’m stuck in understanding the correct way to do this and if this is the correct command to be used.
I would greatly appreciate your help !
Thank you in advance.
