Dear Douglas, What should I do next? I do not know how to use the freesurfer to calculate the correlation different of two group. So could you give me some advice? Yours Linda

Dear Douglas, OK, I will figure it out. And my next question is that, What should I do next? I do not know how to use the freesurfer to calculate the correlation different of two group. So could you give me some advice?

Surface-based analysis is an alternative to talairach-based analysis. It does not make sense to do both. Is the AFNI talairach space affine (ie, 12 dof)? If so, then it is possible to undo the resampling to talairach space. You will need to know which space the afni results are in (ie, MNI152 or MNI305 or something else? 1mm or 2mm?) doug

Dear Douglas, I do not understand what's your meaning? Yes I think the afni results has already alined to T1.mgz, so it is already in talairach space. I do not know what to do next? As I have two groups subjects. I do not know what to analysis the correlation different between two groups by using surface-based analysis of freesurfer.

Are the AFNI results already in talairach space? If so, then there is no point in going to surface space. doug

I get the correlation result between two condition of the functional data by using AFNI( I do not know how to do correlation by using freesurfer) And then I use the bbregister to aline the correlation result (produce by Afni) to the anatomical result produced by using freesurfer. Next I using mri_vol2surf to aline the each one's functional result to the fsaverage offer by freesurfer. My question is :1 Should I need to do mri_vol2vol next for each subject? 2 I have two group of subjects. I want to know if there is some correlation different between them? What should I do next? Thanks very much! Linda
