Thanks Doug, this makes sense. What about retinotopic mapping? Should I use fsaverage or self?

It should either be fsaverage, or self, or an average subject you have
created. The fMRI analysis is done such that the raw data are resampled
into the fsaverage space (unless you use self) and processed there in
anticipation of doing group analysis.
