During the Spring Freesurfer workshop the newest version of Freeview was used as the primary viewing tool.  Are there compatibility issues with using the newest version of Freeview while running analyses in an older version of Freesurfer (v5.1.0)?  That is, if you run recon-all through v5.1.0, can you view and make manual edits using the newest release of Freeview (11 May 2014 build) or should you only use the Freeview build that is specific to your Freesurfer version (22 May 2011 build for 5.1.0)?
