How did you edit the registration? Does it work with the unedited version?

Hi Doug,

One more question about feeding the -reg to mri_vol2surf, please.

I am specifying the registration .lta because I have made edits to it,

mri_vol2surf --src FS6_24551_MPRAGE_Neuro.nii/pet/pet2free_fsl.mgz --out FS6_24551_MPRAGE_Neuro.nii/surf/lh.PETSurfce.mgh --projfrac 0.5 --hemi lh --reg FS6_24551_MPRAGE_Neuro.nii/pet/pet2free_fsl.mgz.lta --trgsubject fsaverage

I get the following error:

ERROR: source volume is neither source nor target of the registration

This error does not appear when I use --regheader though?

Best Wishes,
