I have a custom overlay on the left hemisphere of fsaverage, I wanted to resample that overlay onto the right hemisphere. I thought it would save time to run xhemireg once for fsaverage, and then resample the left and right fsaverage overlays onto the left and right hemispheres for all my subjects.
Instead, I can run xhemireg on all my subjects, and then resample the left hemisphere overlay of fsaverage to the left and /xhemi (right) hemispheres for each subject. It will take a bit longer, but it should be fine.

why are you running xhemireg for fsaverage?

I updated all the xhemi scripts following: http://www.freesurfer.net/** fswiki/Xhemi http://www.freesurfer.net/fswiki/Xhemi but unfortunately the problem persists for fsaverage, since norm.mgz does not exist for fsaverage. I'm going to try creating norm.mgz for fsaverage to see if xhemireg works. Even if it doesn't, xhemireg does work for my other subjects, so I'll be able to find a solution.
Thanks for your help,
Andrew

when did you update the xhemi scripts last? Do a search on our wiki for xhemi to get pointers to the most recent ones On 10/02/2012 01:59 PM, Andrew Bock wrote: Thanks Doug!

When I run xhemireg I receive the error "ERROR: Option --keep-precision unknown" I looked for the newer version of mri_vol2vol described in the previous post, but could not find it on the ftp site. Any suggestions?
