[Freesurfer] Regarding mri_path2label in computation of gyrification index

Hi,

I am trying to compute gyrification index step by step for my dataset using the guidelines outlined on the website to compute lgi. I'm stuck at the step of mri_path2label command. What is the exact command to create a?h.pial.*.label file from?h.pial.*.path and?h.pial.*.center file?

mri_path2label --(?) ?h.pial.*.path ?h.pial.*. center ?h.pial.*.label

If I use --singlepath I could create *. label files but the results don't match the output created from recon_all -compute_lgi.

Secondly, what is the meaning of the error MRIS‎alloc:nfaces=-8<0.

Thank you for any help.

Sincerely

Virendra
