[Freesurfer] Problems converting annots

Hi all, Sorry to keep pressing this issue, but I am really stuck and need to sort this out before I can progress. I have been generating some customised annotation files, generally with 500 or more ROIs. The parcellation is done on a per hemi basis, meaning that there will not always be the same nu

[Freesurfer] Mri_label2vol memory error

Hi all, I've tried running mri_label2vol on a few different computers now and keep encountering the same memory error. Can anyone provide suggestions as to how to get around this problem? I've included the output from a run using linux on a dual 3.05 GHz Xeon with 8GB ram below. Thanks for your hel

[Freesurfer] surf2surf for annots

Hi all, I have a custom annot in fsaverage space that I would like to map to the surface of each of my subjects. I have 2 questions about how mri_surf2surf does this: 1 - Does it use the surface-based registration performed in autorecon2, or is it a volume-based registration? 2 - If it is a volume

[Freesurfer] Anatomical stats for fsaverage

Hi, I'm playing around with different ways of generating custom annotation files using the fsaverage surface, and would like to estimate the surface area of each ROI. I tried running mris_anatomical stats, but it seems to required wm.mgz, which is not contained in the fsaverage directories (please
