This page describes how to update Freeview within a FreeSurfer v6 installation. On Linux this involves updating a single file in your FREESURFER_HOME/bin directory. On Mac it involves replacing the folder in your FREESURFER_HOME directory. A backup should always be made of the file (or directory) before it is replaced.

Please note the development versions of Freeview will contain the most up to date features but lacks the rigorous testing done before a major release. Therefore, it is imperative that you back up your existing version before replacing it with the development version.


  1. Go into your $FREESURFER_HOME/bin and create a backup of your existing freeview.bin file (this may require sudo access):

    cp freeview.bin freeview.bin.BKP
  2. Download the latest "development version" of Freeview using the following link. Again, overwriting the original freeview.bin file may require sudo access:


  3. Make sure the new freeview.bin file is made executable. This is acheived via the following command:

    chmod a+x freeview.bin
  4. You should now have the new freeview application which is opened by typing freeview on the command line (after sourcing Freesurfer):
