Re: [Freesurfer] Xhemi: vertex-wise volume asymmetry analysis?

OK, you're using an older version that did not copy the volume. You can just do this cp subject/surf/lh.volume subject/surf/rh.volume Note the change from lh to rh! doug On 04/28/2014 06:25 PM, Yizhou Ma wrote: Thanks Doug. I don't see an error message in xhemireg.?h.log files. Please

There should be a ?h.volume file. Are you sure there is not? You can specify -meas volume when you run mris_preproc doug On 04/27/2014 08:35 PM, Yizhou Ma wrote: Dear freesurfer experts, I am working on a project on cortical asymmetry and I have analyzed vertex-wise cortical

Thanks Doug. I have ?h.volume in subject/surf but not in subject/xhemi/surf. I followed this page http://surfer.nmr.mgh.harvard.edu/fswiki/Xhemi and I think it is a problem with surfreg rather than mris_preproc. Can I just copy the ?h.volume from subject/surf to subject/xhemi/surf? Best, Cherry

Hi Doug, I just read from the .log files that the lh.thickness/area/pial/... files in subject/xhemi/surf are copied from subject/surf at the end of the command. Thus it seems that I can just copy lh.volume, too? Thanks, Cherry On Mon, Apr 28, 2014 at 6:25 PM, Yizhou Ma ym...@nyu.edu wrote:

Dear freesurfer experts, I am working on a project on cortical asymmetry and I have analyzed vertex-wise cortical thickness/surface area asymmetry. However, I noticed that Freesurfer doesn't not seem to facilitate such analysis for gray matter volume, as after running surfreg -xhemi there is no
