Hi Rick,
I am not clear about the pipeline of group analysis on the surface.
1. In which step should I map data to standard mesh surface?
- Like the single subject surface analysis, after motion correction? By replacing subject surface with standard surface in afni_proc scripts?
- Then what is the -surf_anat of the standard surface? Using the same -surf_anat as in single subject surface analysis?
- Can I map the single subject surface analysis results(stats.subj.?h.niml.dset) to standard mesh surface directly? By 3dSurfToSurf?
2. Which standard mesh surface should I choose?
- Why these sulcus on the same standard surface called std.141.subj_both.spec of different subject look very different? (Like original surface. )
- Then the std.141.subj_both.spec of which subject should I choose to show the group results?
- And some use MNI305 FsAverage brain as template surface, is it better? How to use it in afni manner?
Thank you,
