Hi Andrew, use mri_vol2vol with the --tal --talres 2 or 2mm option (or --talres 1 for 1mm isotropic) option. This will put it into an MNI305 space. So something like
mri_vol2vol --reg register.dat --mov yourvolume.nii --tal --talres 2 --o yourvolume.mni305.nii
If you did 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.

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 registration so that I have a matrix that registers the functional images to the mni305 volume. I've been using the following, but registrations aren't coming out properly:
mri_matrix_multiply -im register.dat -iim <subject>/mri/transforms/talairach.xfm -om reg_to_common.dat
I'm checking them using tkregister2, but the results don't look great. Is there a better/easier way to do this? Thanks!
