Hi Doug, mri_label2vol says it creates an mgz from a label, I need to do the reverse. I'm starting with a mask_MNI.mgz (brought from FSL's MNI space via mri_convert) and I need to be able to use that mask to extract thickness from the individual subject.
Also, mni152reg fails because it expects to write a tmp file into an FSL directory rather than a Freesurfer directory. The FSL standards directory is write protected for obvious reasons. Can I redirect the temporary file? Error message: “mkdir: /usr/local/fsl/data/standard/tmp.fslregister.9446: Permission denied”

Hi Ruth, run mni152reg for each subject to create a registration from the subject to the 152. Then use mri_label2vol to map the mask into each subject's space.

Doug, I'd like to get them into the individual's space, but I assume I have to get there by way of fsaverage? Final goal is to have a regional thickness measure for each individual subject. Ruth Carper

Do you want to transfer them to fsaverage space or to the individual anatomical space? doug

Hi, I'd like to take some masks that I have in MNI standard space in FSL and map them to Freesurfer surface space. The goal is to extract measures of average cortical thickness (or area or etc) for those regions for each subject. Is there a standard way to do this?
