the decimation code only finds equally spaced points, I don't think it generates a tesselation. One way to downsample is to map onto on of the ico surfaces, then pick the first n points, where n is one of the downsampled icosahedra. Otherwise, I think there are other people who have written surface downsampling packages.

Hi:
I am trying to generate a down sampled tessellation file from inflated pial in TkSurfer. I used write decimation in tool->surface menu, and can find vertices. How can I fill the boundary of those points, and save the vertices and faces, so that I can get a new .tri file?
Thanks a lot! _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
