Hi all,
I know this is slightly outside the normal bounds, but I am wondering if there is a way to create a surface from the skull? One of our folks is looking to create some custom-fitted recording chambers for nonhuman primates based on the individual skull. I seem to recall that FS has a way of generating STL files, which would be perfect for submitting to a rapid prototyping machine. Here's what the user says:
" In brief, I would like to shape the bottom-side of my recording chambers (elliptical/circular cylinder) so that they form-fit to the curvature of the primate skull. Ideally, this will involve segmenting and extracting a 3D portion of the skull and converting it into an STL file to use for machining the implant."
Best,
mjp
Hi Mark,
you might check Matti Hamalainen's MNE website. He uses the watershed code to generate boundary models, including skull. Or just try out mri_watershed with -surf I think (it's covered in the help, at least a bit)
cheers Bruce

also, once you get a surface file, then mris_convert will convert to .stl format, which we've used in 3d printer applications.
if you can get a skull from mri_watershed, then mri_tessellate will make a surface. mris_smooth and mris_keep_main_component are two other useful utility to clean things up.

Thanks for these suggestions - looks promising so far!
