aparc.annot is Rahul Desikan, et al's, and a2005s is Christophe Destriux's. Both were derived from a group of brains labeled by hand. They are fairly different in the detail (Christophe's is very detailed). You can use either one.

Greetings,
We are using fsaverage as the template for overlaying our group fMRI data. Which annotation file should we use for designating ROIs? There seem to be two options: lh.aparc.a2005s.annot and lh.aparc.annot. And which atlas is each annotation file derived from?

Thank you,

Dara
