Dear Freesurfer experts Hi
I was trying to do selxavg in native space for individual subjects which I have analyzed them in "fsaverage" space before. I have two sessions of functional data for each subject. In order to register them on one T1, I put the functional data from both sessions in one bold folder and registered all of them to one T1. The maps that I acquired from these analysis are slightly different from "fsaverage" maps. In "fsaverage" analysis, I analyzed each session separately (selxavg) and then concatenated (isxconcat) the two sessions at the end. I believe it is not possible to do this in "native" space, since I have to register all the functional data to one T1, right? I need to know what is causing the differences in "native" and "fsaverage" maps? I appreciate if you could reply. Thanks a lot Mona Zahra (Mona) Nasiriavanaki Postdoctoral Research Fellow Martinos Center for Biomedical Imaging Massachusetts General Hospital 149 13th Street, 149-2615 Charlestown, MA, USA, 02129
