mesh referential units
Posted: Wed Jun 06, 2012 7:41 pm
Hi
From a minc MRI file I created .mesh file with brainvisa ( for example a head.mesh). I would like to extract the vertices coordinates for the .mesh file ( to use it into matlab)
QUESTIONS:
I would like to know if the coordinates of vertices stored in the .mesh file are in mm or in voxel ??
If there are in voxel:
Is the origin [1 1 1] or [0 0 0] ?
Does the voxel coordinates be necessary integers ?
PS:
if we take a head: I figured out that the mesh referential is x: Right-->Left y: Anterior--> Posterior z: Superior --> Inferior with the origin in the Right Anterior Superior corner
I am wrong ?
Best regards
Alexis
