Dear FreeSurfer experts,
I apologize in advance if my questions seem naive or too simple: I am completely new to FreeSurfer and I am still attempting to understand how to make good use of its potential.
I believe I want to use it in an unusual way. I have been given two cortical surfaces, both in the form of genus 0 triangular meshes. The two meshes are stored as OFF files, but I can easily generate other formats (PLY, OBJ, simple ASCII, ...). For both surfaces I also have informations on some sulci, in the form of list of vertices, in ASCII format.
I would like to map (register) one mesh onto the other: it seems that FreeSurfer would allow me to do this with the following steps: - inflate the two surfaces - map them onto the sphere - register one surface (on the sphere) onto the second surface (on the sphere).
How do I make this work? I have looked at "SurfaceRegAndTemplates", but the process described relates to specific FreeSurfer files. I will obviously need to convert my OFF files into a format that FreeSurfer can recognize, and vice versa convert the sphere representations (Source mesh, S, target mesh, T, and S on T) into an ascii format that I can analyze. Could someone give me an overview of how I should proceed, with pointers on which procedures I should use from FreeSurfer.
Thanking you in advance for your help,
Best regards,
-Patrice
