Hi all, I'm using the mri_watershed instruction to extract the skull and skin mesh, because I'm using them in a boundary element method, but the dimensions of these meshes are too big for my application (20480 faces and 10242 vertices for each ones). Do you know if there is a way to define a maximum mesh size for the mri_watershed instruction (or at least an equivalent instruction in which is possible to do it) ? I need of very coarse meshes ( 1000 faces for each ones for example).
Thanks!
Hi Tommaso,
I am not sure about freesurfer, but why don't you simply use a standard tool for mesh simplification e.g. qslim http://graphics.cs.uiuc.edu/~garland/software/qslim.html probably there are more.

Thank you Martin, I only wanted know if there is a way to do this without using an external program. I will try using a standard tool.
