THere are two sets of coordinates that are reportable. First, the mni305. This is the coordinate system that we use internally (eg, surface coords of fsaverage are stored in mni305). We can convert these coords to "talairach" thru Matthew Brett's transform. This is what is reported in the "Talairach" field in tkmedit and tksurfer. Does this answer your question?

Hi,
I've been asked to report Talairach coordinates in a paper, but I've been told that the coordinates that are listed on the fsaverage brain (in the talairach.xfm file) are not accurate. Does anyone have a way to get the true Talairach coordinates on the fsaverage brain?
Thanks,
Matt
