Hi Bruce, Thank you for your reply. I coregistered the new data beforehand in SPM (to the structural of the old session). So I didn't do anything to the label. I displayed the structural with tksurfer-sess -c eccen -fthresh 0.5 -a rtopy.self.lh -s P2_BK (since I wanted to display my eccentricity data) and loaded the label just by clicking load --> label. Should I add -reassign in this tksurfer command, or is there a way to load the label with a command, to which I have to add -reassign?
Also, I'm not familiar with freeview, I tried starting it by typing 'freeview' but I get the error: freeview.bin: error while loading shared libraries libXss.so.1: cannot open shared object file: No such file or directory. It doesn't seem to depend on which directory I'm in. Thanks, Bianca On Wed, Jul 10, 2013 at 5:19 PM, Bruce Fischl <fis...@nmr.mgh.harvard.edu>wrote: > Hi Bianca > > how did you coregister the data?
