Inner/outer meshes with corresponding vertices #114

Actually, you can use a similar formatting, the first new module of nighres' first version did just that. I'll check on the code and add it to the next version. Basically (if you want to write it yourself), you sample profiles from surface vertices and just copy the topography. Note that FS does it differently, adding a lot of tangential movement to make the mesh nicer.. |
Yes. Bruce Fischl gave a nice talk about this on the "Brain in Depth" workshop in Leipzig last Monday. They are now experimenting with 'vector fields' rather than use the Laplacian profile.
I'd be happy to try this, but could you give a little bit more detail? |

In nighresjava there is a LaminarProfileMeshing function, which does exactly what you want. It takes a surface mesh (point coordiantes, triangles) and the layer surface image from the volumetric layering and outputs a family of meshes at the corresponding depths, all with the same topology. |
Hey guys,
I was wondering: I would like to use nighres to make surface meshes that I can use in pycortex.
However, their infrastructure is based on
Freesurfer, which makes it necessary that the vertices of the pial mesh have corresponding vertices on the white matter mesh. Am I correct to think that using the levelset-approach of nighres this cannot work?Cheers,
Gilles
