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
