[Freesurfer] Hippocampal subfield segmentation with T1 and T2

Hi all, I've been trying to run the hippocampal subfield segmentation with T1 and T2 images, and haven't had much luck. I had previously run recon-all on all my scans in v5.3, but testing on one subject I re-ran recon-all with the additional T2 scan, and that seems to have run fine. However, when

Re: [Freesurfer] PET partial volume correction

It is a little tricky because you don't want to use different masks for different subjects. I recommend using CVS where I've created a subcoritcal mask in 2mm space (mri.2mm). So the idea would be that you map your subcortical MG map to CVS space, then smooth it (mri_fwhm) specifying the

Dear Dr Greve, Thank you so much for the quick response. Just to confirm that I understood the procedure correctly. The analysis is volume based (i.e. voxel-wise) for the subcortical structures using mask created by freesurfer's "mri_binarize" for these regions. Correct? Original
