Hi Franz, try mapping the xyz coordinates of the individual into fsaverage6 (or fsaverage5 or lower) space. This should solve both of your problems (I think). doug

Dear FS experts,
I would like to downsample a subject's white surface to arrive with a smaller number of vertices in order to feed the surface into FSL's surface tracking.
I tried to map the fsaverage6 onto the single subject: mri_surf2surf --hemi lh --srcsubject fsaverage6 --sval-xyz white --trgsubject s01 --trgsurfval white.ico6 --tval-xyz --trgicoorder 6
If I load it into tksurfer, the surface now looks (as expected) much coarser. However, the number of vertices is still ~ 130k.
Furthermore, it would be great if vertex x would spatially correspond in all subjects.
Any advice is much appreciated, Cheers, Franz _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
