Oh I just used that option instead of providing a registration file, which I don't have.
I need to turn the two surfaces into a single volume.

Hi Vale

mri_surf2vol is to take take from the surface to the volume within one
subject. Why do you need a trgsubject? You can compute the registration
with e.g. bbregister. Maybe I'm not understanding what you are trying to
do....
