there is -1 switch you can give mris_register to directly register one surface to another, but in our experience using the atlas statistics and the measures of cross-subject variability  stabilizes the whole procedure

Hi, Douglas,

Thank you so much for your help.

I once ran the recon-all for my subjects and I got the 'xx.sphere.reg's.
Are these results the warped sphere surfaces to the atlas?

I am trying to register the wm surface of subject1 to surface of subject2,
so I am seeking for help to use 'mris_register'. Can I use another tool
to do that?

Thank you again.

Best,
Xiaojing

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
