[Freesurfer] Ridiculous story about Freesurfer

Did anyone else happen to see this ridiculous story on Gizmodo today? http://gizmodo.com/5919149/your-brain-scan-looks-different-on-mac-and-pc It cites the recent article The Effects of FreeSurfer Version, Workstation Type, and Macintosh Operating System Version on Anatomical Volume and Cortical

Re: [Freesurfer] mri_matrix_multiply to move functional images to common space

not create the register.dat with bbregister, I would strongly suggest it. It works really well on the partial volume files. If you do, you should specify your current register.dat as the init registration. doug Andrew Dumas wrote: Hi, I'm trying to move a bunch of partial FOV functional

[Freesurfer] mri_matrix_multiply to move functional images to common space

Hi, I'm trying to move a bunch of partial FOV functional images (occipital cortex only with oblique coronal slices) into common space. For each subject, I have a registration file (register.dat) to register functional images to anatomicals, and I'd like to incorporate the talairach.xfm

[Freesurfer] Big Ventricles on v4.0

Hi everyone, I'm using a frozen version of FS v4.0 and I have a subject with rather large ventricles that don't get filled properly (surfaces and aseg are off) during recon. I can't really find a good fix in previous messages besides to upgrade FS, since it seems like the newer versions will

[Freesurfer] Convert annotations longitudinally

[Freesurfer] Calculating BPF

Hi, I've been looking through the mailing list archives for anything on calculating BPF (Brain Parenchymal Fraction) and have only found some fuzzy descriptions of how to calculate this using FreeSurfer. I know I can get ICV from the aseg.stats, but how can I obtain the volumes of total white and

[Freesurfer] Partition a surface

Hi! I'm trying to partition a surface into a number of random but roughly-equally sized areas, and I've been using the mris_make_face_parcellation function to do this. Is it possible to have a finer control over the sizes of each label it generates? I only see 7 options in:
