I manually merged hemispheres for white and pial surfaces with gmsh (http://geuz.org/gmsh/), but it doesn't work. The merge is not consistent, and cells are not re-computed.
I've thrown a question to the freesurfer's mailing list. We have mri_tessellate
and mri_mc
. The first one just puts a vertice on each corner of the on voxels. The second runs a marching cubes algorithm (https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2011-November/021391.html).
Another good ref: http://brainder.org/2012/05/08/importing-freesurfer-subcortical-structures-into-blender/
It seems sensible to use mri_pretess -> mri_tessellate -> mris_smooth
OK, I have a pipeline to generate the CSF mesh. This is how it looks:
It looks much better when overlaid on the T1 (after resampling this structural in the dMRI space):
I upload the new code, then I will check that everything works correctly.
Not to miss this question: https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2013-June/030586.html
Generate CSF surfaces for the real data example. Probably, a good idea to take a look on: https://github.com/nipy/nipype/pull/307
I also recall here an email from @meribach on April, 30th:
