Hi Sourena
I'll try to take a look this week. As I said it's really an alpha version (if that). If you are downsampling a voxel segmentation why not just use vol2vol?

Hi Bruce,
Thanks. But when I use mris_map_cuts on the original white surface, the output is: "MRISreadPatch: bad vertex # (1701060705) found in patch file" I guess that some preliminary job should be done before feeding to the command? As an alternative, is it wise to extract all .aparc labels and then merge them with mri_mergelabels to have a single full cortex label file?
(For downsampling, the goal is to bring FSL FIRST subcortical T1 segmentation down to DTI resolution.)
Cheers, Sourena

Hi Sourena
You can try mris_map_cuts, which I wrote a while ago, but haven't used very
much (hopefully it still works!). For the downsampling, I think Rudolph had
something. If not, we can modify surf2surf to avoid using the sulc if some flag is specified. Rudolph?
cheers Bruce

Hi experts, I have two (unrelated) issues. I am seeking a command-line method to remove non-cortex vertices and triangles from a surface. I have seen the manual method with tksurfer, but perhaps this is not suitable for larger datasets?
I have tried to use surf2surf for downsampling of the meshes NOT generated by Freesurfer into icosahedron, to no avail, maybe because this command seeks to map the .sulc data which is absent in the alien mesh. Please let me have any advice for this goal if basically possible with available freesurfer tools.
