External Email - Use Caution
Dear list,
I would like to register volume data from several subjects to a common volume, e.g., the volume of the fsaverage subject.
The volume data contains some marked voxels and is in the same space as the orig.mgz of the respective subject. I would like to find/see the positions of the voxels in a volume like $FREESURFER_HOME/subjects/fsaverage/mri/brain.mgz.
This would require a non-linear, inter-subject registration I guess. How can I do this in FreeSurfer? Most likely I can somehow use mri_vol2vol to achieve this, but I don't see how. Is the talairach transform what I want?

Nevermind, I think I got it to work:
mri_vol2vol --mov subject_x_samples.mgz --s subject_x --targ $FREESURFER_HOME/average/mni305.cor.mgz --m3z talairach.m3z --o subject_x_samples_in_mni305.mgz --no-save-reg --interp nearest
If anybody could confirm that this makes sense, I'd still be grateful. ;)

that looks right to me
