Hi all! I’m trying to redo some analysis from my lab from volume based analysis to surface based. I’m not super familiar, so please pardon my lack of knowledge here. Thank you.
I have some T1 anatomy images from different subjects, and corresponding beta maps in the functional space. I need these ultimately to be in the same space for group analysis on the beta values. For a quick first pass, I plan to just convert the beta maps to mni space using the registration provided by flirt and use nilearn’s vol_2_surf to sample it on fsaverage. Is this generally ok? I assume there would be loss in quality, otherwise people won’t be doing recon-all which takes forever, but how much worse is it in your experience?
