either way should be fine, although we have a new robust registration developed by Martin Reuter and incorporated into the current recon-all that we are now using for motion correction that we believe produces slightly more accurate results than standard motion correction

Dear Freesurfer experts,

We have acquired 2 sets of MPRAGE images in a single session to be averaged before processing in freesurfer. Is it valid if I use fslmaths command in fsl to average images and then feed the averaged image into freesurfer? Or do you recommend an equivalent of fslmath in freesurfer?

I really appreciate your input on this issue.

All the best, Arman _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
