Hi Guys, I read in the sidenote here (https://surfer.nmr.mgh.harvard.edu/fswiki/SurfaceRegAndTemplates) that inter-subject surface base registration using mris_register and -1 flag performs a sort of rigid registration. So I tried it between two of my subjects with the command below
mris_register -1 -curv P00001639/FreeSurferClean/surf/lh.sphere P00001639/FreeSurferClean/surf/lh.sphere lh.sphere3.reg
and got the results (see the attachment). It is clear that the registration output is just a shifted version of the source. Having this confirmed I want to know if there is any way to force the mris_register to perform a complete non-linear surface based registration for inter-subjects registration the same way it does for template.
I have to mention that I visualize the lh.sphere3.reg using freeview and loaded the sane lh.curv on that surface. I hope I’m not doing anything stupid.
