This page describes how to update Freeview within a FreeSurfer v6 installation.
Linux
Go into your $FREESURFER_HOME/bin and create a backup of your existing freeview.bin file (this may require sudo access):
cd $FREESURFER_HOME/bin cp freeview.bin freeview.bin.BKP
Download the latest "development version" of Freeview using the following link. Again, overwriting the origin freeview.bin file may require sudo access:
Make sure the new freeview.bin file is made executable. This is acheived via the following command:
$FREESURFER_HOME/bin chmod a+x freeview.bin
