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
