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
