Hi! Well, as far as I know: - both are MNI standards ---- Colin27 is the MNI Colin27 single subject standard ---- fsaverage is MNI305
My problem with fsaverage was that I couldn't use the transformations made with the registration matrix after spmregister or bbregister, but I understand that it depends on the application. This is the reason I used the alternative way through Colin27 (since both are the same brain, one in 2mm and the other in 1mm, the registration matrix was almost 1). Saying that, I understand that if you want the AAL .labels in fsaverage, you always could use mri_label2label in order to transform every label to fsaverage. I don't know what is the best method, maybe some expert in the list will be able to confirm this step, but it is definitely what I would do. If you are thinking using qdec or some other tool with fsaverage, I understand that you could always create your own average and transform the data there or create the data with mri_surf2surf for Colin27 (this is going to be our approach). hope this helps!
