Dear Burce,

I have 20 normal subjects, and I want to do inter-subject surface-based registration to all of them. So each one's surface can align properly to the other subject’s surface. After that I can put the functional data onto the surface which has aligned to each other already.

And now I followed the process of creating a registration template from scratch(GW)(https://surfer.nmr.mgh.harvard.edu/fswiki/SurfaceRegAndTemplates) to do the surface-based registration. Round 1, all reference subjects data are registered to the initial template, producing ?h.sphere.myreg0. (I've coordinated the suffix numbers with the template used to produce the registration.) Using that registration, a new template (mytemp1.tif) is made using all reference subjects as input. Round 2 is essentially a repeat of Round 1, but produces an improved template (mytemp2.tif) because Round 2's initial registration step is based on a better template than in Round 1.

I get the lh.sphere.reg.newtemplate1 and rh.sphere.reg.newtemplate1 in each subjects's surf folder. I do not know how to check the result about if every subject has aligned to each other properly. And I do not know what should I do next.

My question is :
1 How can I check about the result as if every one has aligned each other properly?
2 And what should I do next, I can not know if the functional data can aligned to the new surface properly. If I can use mri_surf2surf or mri_vol2surf can be used for this.

3 The lh.sphere.reg.newtemplate1 and rh.sphere.reg.newtemplate1is just for sphere, and how about the inflate aligned to each other?

Yours Yufeng
