Hello all
I would like to know what kind of coordinates (RAS, Talairach, Spherical) are saved in the AsCII file resulting from:
mris_convert lh.sphere.reg lh.sphere.reg.asc
I could not find correspondence among the resulting coordinates and those that are shown in Tksurfer.
If they are not the spherical ones, how can I get an ASCII file with the spherical coordinates ( XYZ) or (Rho,Theta) in order to work on the spherical world?
In advance Thank you a lot

It should be the spherical. Why do you doubt it? One way to check is to compute the radius at a few of the vertices (it should be the same for all vertices).

Ok,
Is there any function to resample the spherical surface data in a regular equiangular grid?
Best regards Jorge

Use mri_surf2surf and resample to an icosahedron (eg, ico7).

Hi Jorge,
they would be the spherical ones.
