Look at http://surfer.nmr.mgh.harvard.edu/fswiki/Xhemi if you want to compare all subjects, then you'll need to do this for all subjects not just the ones you want to flip On 03/28/2016 02:30 PM, Ajay Kurani wrote: > Hello Freesurfer Experts, > >I processed all of my brains through freesurfer

You should use xhemireg. Just changing the sign of the x coordinate will not be meaningful. On 03/29/2016 12:49 PM, Ajay Kurani wrote: > Hi Doug, >I used the caudate surface I created as an example as I was testing > the command out. I do not plan to use this command for the caudate. > It

Hi Doug, I used the caudate surface I created as an example as I was testing the command out. I do not plan to use this command for the caudate. It just happened to show the same issue as the earlier post ( https://www.mail-archive.com/search?l=freesurfer@nmr.mgh.harvard.edu&q=subject:%22\[Fre

hmmm, we don't have a caudate surface. How did you make it? mris_reverse just changes the sign on the x coordinate. This might not show up "properly" in freeview; it does not surprise me that it could appear to be 1 voxel off. This was not the intended use of this program. xhemireg will not hel

Hi Freesurfer Experts, In testing mris_reverse, there seems to be a voxel shift. In looking up other freesurfer utitlites I came across xhemireg and surfreg. https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2014-September/040573.html Does xhemireg or surfreg call out mris_reverse, causin

Hello Freesurfer Experts, I processed all of my brains through freesurfer 6.0 dev for Linux and warped the surfaces to standardized space. For a handful of subjects I want to perform a left right flip of the cortical thickness files (standardized space) for a group analysis. What is the best
