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
