I am attempting to register a ROI (.nii) to the surface of fsaverage to get the statistical output on the cortical thickness. I followed your instructions on MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness but after mri_vol2surf I get this message, I can’t visualize the ROI on the surface. I I’m using Freesurfer 7.0.1. How can I solve this? Thank you, Alina Rojas.
