spmregister and fsl_rigid_register will only use one time point (1st) from your functionals to compute the register.dat. Or extract the one time point you are using for motion-correction.

Does AFNI have an automated coregistration tool? I thought you could only do manual coreg in AFNI. The problem I have with coregistering in SPM is that I have a 4D BRIK of 298 functionals. Coregistration in SPM reslices all of these functionals into anatomical space, making them enormous files. It seems that AFNI won't let me convert these huge files back into a 4D BRIK.
Quoting Graham Wideman gwlist@grahamwideman.com:
Nate:
Is there a reason you don't want to coregister them with AFNI's coregistration?
Regardless, AFNI also has a program to covert AFNI format to ANALYZE format data.
Be aware however that AFNI supports all 48 possible data orders, while ANALYZE does not... so keep good track of the right-left aspect of your data.

Hello, I was wondering if anybody has any insight into the best way to coregister functionals with anatomicals in Freesurfer. I am looking for an automated method of coregistration. I noticed the spm_coregister command, but I am working with AFNI BRIK files, and I assume this requires Analyze format.
Any
suggestions?
Thanks.
