there is not an mri_spmregister (there is spmregister). If you have an FA map, then I would use bbregister On 2/25/17 8:03 PM, John Anderson wrote: Hi Doug, thank you for the detailed response. Highly appreciated! Kindly. I want to register FA map to structural T1 image using the command

Hi Antonin, mni152reg was just meant to replicate the affine registration used by other software and to provide users with a fast-and-easy way to do volume-based (subcortical) analysis in FS. I would prefer to use CVS for everything, but, as you mention, it does have a huge computational

Dear Doug, thank you for the feedback. In this context I would like to ask you to share your opinion on the mri_cvs_register. This tool should be far the most accurate for the registration to MNI, than any of affine-based registration tools, shouldn't be? Are there any pitfalls/disadvantages

I have not actually tested it on the mni152 reg. It might (probably does) work fine. On 2/25/17 5:33 PM, Antonin Skoch wrote: 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.

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.

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

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
