Hi I am sorry if my question is really basic, but I am choosing the seeds for fsfast resting state connectivity analysis, and I am looking at the different options in the litterature. Seeds are often presented with the talairach coordinates, and I was looking for a way to find the corresponding vertex number on fsaverage surface, so that I can build the corresponding label that I could use for the fcseed-sess command. I found this previous email, and there seem to be a command to do that but I don't know how to launch this command select_talairach_point <xtal> <ytal> <ztal> Thank you very much Celine
