Dear Freesurfers, I've generated individual polar, eccentricity, and fieldsign maps for each of my subjects. I would like to generate group average maps of these that I can visualize on the fsaverage brain.
When I ran: isxconcat-sess -sf sessid -analysis rtopy.self.lh -o group_lh I got: ERROR: analysis space is self surface, not supported How do I do a group average for the 3 different maps? Thanks. Michelle For each person I ran recon-all and flattened occipital patches. Then: mkanalysis-sess -a rtopy.self.lh -surface self lh -TR 2 -retinotopy 48 -paradigm rtopy.par -nskip 4 -fwhm 0 -fsd bold -force mkanalysis-sess -a rtopy.self.rh -surface self rh -TR 2 -retinotopy 48 -paradigm rtopy.par -nskip 4 -fwhm 0 -fsd bold -force preproc-sess -surface self lhrh -fwhm 5 -per-run -s sjXX -fsd bold -force selxavg3-sess -a rtopy.self.lh -s sjXX -force selxavg3-sess -a rtopy.self.rh -s sjXX -force fieldsign-sess -a rtopy.self.lh -occip -fwhm 20 -s sjXX fieldsign-sess -a rtopy.self.rh -occip -fwhm 20 -s sjXX
