The surface-based registration is usually done as part of recon-all (which runs mris_register with all the appropriate arguments). You trying to do something different?

Hi, all,
 I am new to FreeSurfer world. I am trying to do the surface-based
registration using FreeSurfer. I found a tool called mris_register,
which is defined as a command registering a surface to an average
surface template(or another single-subject's surface). But I don't
understand how to use this command.
 Are the inputs often xx.sphere? I have two wm surfaces 'subj1.smoothwm'
and 'subj2.smoothwm' and I want to align them. Can I use
mris_register to do that? What information or parameterization are required
by mris_register? Since when I run this command, I get errors saying
that:
"reading template parameterization from target.smoothwm
 HIPS unsupported
 No such file or directory"
 I don't understand what this error means. Could anyone help me?
Thank you so much.
 Best,
Xiaojing
