Dear FreeSurfers,
I have a question regarding the installation of xhemi (I am using FreeSurfer 5.1)
I tried to follow the guide on: https://surfer.nmr.mgh.harvard.edu/fswiki/Xhemi to install the necessary files, however the following files do not seem to be present on the ftpserver:
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/surfreg ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mris_preproc ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/fsaverage_sym.tar.gz ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mult-comp-cor.tar.gz ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_convert.{linux,mac} ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_vol2vol.{linux,mac}
What could be wrong?
Thank you very much!!
Kind regards,

Dear Free Surfers,
I have a short question regarding the mapping of vertices of the fsaverage_sym, how do vertices in the left hemisphere correspond to vertices in the right hemisphere? When I tested it, it did not seem that the first-indexed vertex on the left hemisphere corresponded to the first-indexed vertex on the right hemisphere defined by me as : (total vertexes/2 + 1) if so, how to calculate the difference between lh and rh?
Thank you very much!!
Kind regards,

Hi Sofie,
no, they don't correspond. You need to use mri_surf2surf to map one to the other (which is a bit tricky).

To follow up, it is intended that you will map both hemispheres of a given subject to one of the hemispheres of fsaverage_sym (it does not matter which, but we usually use lh). You can then do the comparisons on that hemisphere. Does that make sense? doug
