Try running recon-all on the MNI152. Load the ROI onto the reconned MNI152; load the surfaces as well and make sure that the ROI intersects with the surface, then use #3 below with --regheader MNI152 instead of --reg tmp.dat. You can also specify --trgsubject fsaverage and mri_vol2surf will map

Dear Victor, Sorry for the slow response. 1.5 T is not a problem. Do you have a companion 1mm T1? If no: then the main problem is the main recon stream. If yes: what is the in-plane resolution and orientation? If it’s a high-res coronal, it may help with the subfields. For the thalamus, I’d just u

The original MRI dims were: 256 256 124, and pixel dim: 0.9375 0.9375 1.5 These MRI scans are really old and predate DCMs so I'm not exactly sure how else to extract the data. But there?'s no complementary MR scans included in the FS processing either. ?I have mixed sources saying different th

Thank you, Victor. 1.5x1x1mm is not ideal, but you should be able to run the modules. Just make sure to QC the output. Cheers, /Eugenio Juan Eugenio Iglesias Senior research fellow CMIC (UCL), MGH (HMS) and CSAIL (MIT) http://www.jeiglesias.com From: on behalf of "Zeng, Victor (BIDMC - Kesh
