External Email - Use Caution I did something similar once. There is a paper on MNI152 to fsaverage conversion options (that suggests a pretty accurate, new method) here: https://www.ncbi.nlm.nih.gov/pubmed/29770530/
If I remember correctly, the simplest way, even though it's not terribly accurate, is to use the information on the website that Douglas linked to go from MNI152 to MNI305, then check for the label of the closest fsaverage vertex in the annot.
