Dear Doug,
I was wondering, why do you prefer mni152reg to mri_coreg for gregistration to MNI? According to help, mri_coreg is also able to do 12 DOF registration.

mri_coreg is the FS implementation of spm_coreg (spmregister) both of which use normalized mutual info. bbregister uses the BBR cost function and is preferred for all MRI. For registration to MNI space, we usually use mni152reg (a wrapper around fsl's flirt) On 2/25/17 8:49 AM, John Anderson wrote: Dear Freesurfer experts, I see that the tool "mri_coreg" has been implemented recently in Free Surfer 6 and I really wanted to know what are the differences between the registration tools "bbregister", " spmregister" and "mri_coreg"! Kindly: 1. Are these tools similar? if not what are the differences ? 2. Is there any preference of using a tool over the others for specific type of data. For example: A. If I want to register FA map to T1 image which tool is more robust? B. if I want to register FA map to MNI space which tool is more robust? I highly appreciate your input on this!

Dear Doug,
If I want to create a new volume that is registered to the MNIspace (using mni1525reg), can I mask out other voxels that are not part of the mni template brain? It is a PET volume (already in individual space using bbregister) that has noisy signals in non-brain regions.
Thank you.

You can do the masking with mri_mask

I have not actually tested it on the mni152 reg. It might (probably does) work fine.
