Hi Ajay,
yes, the vertex indexing is the same for all surface configurations of a given surface (e.g. lh.inflated, lh.white, lh.pial, lh.sphere, etc...). The ascii patch file format is as follows:
#!ascii version of patch <surface_file_name> <num vertices> <num faces> <vno> <x> <y> <z> . . . <fno> <vno1> <vno2> <vno3> . . .
where there is one entry for each vertex in the patch, and one entry for each face in the patch.
cheers, Bruce

Hi all,
Using mris_convert -p I converted a ?h.patch.flat file to ?h.patch.flat.asc
I am not sure I understand the file format correctly. Could some one please help?
Also is the vertex indexing of faces maintained througout in freesurfer.
For example if I have a ?h.pial which I convert to ?h.inflated and then to ?h.flat will the vertex numbers remain the same?
Will this hold true even if I export them asc.
Also what is the difference between ?h.sphere and ?h.qsphere ?
