it is ok to spec -surfreg, but is not necessary in this case mris_preproc will change the name when you spec a target subject (eventhough the says that the default is sphere.reg)

Hi Doug,

Thank you for your replay.

I understood that if I did not specify "--surfreg my_avg_subject.sphere.reg"  mri_preproc was going to use the original file (sphere.reg), because in the help of mri_preproc it mentions this:

--surfreg SurfReg : default is sphere.reg

With this in mind,do you think it would not be necessary to specify it in mris_preproc?

What is the difference between sphere.reg and my_avg_subject.sphere.reg?

Best wishes, Marina
