Hi Doug - Yes, there used to be a bug in how freeview used to interpret orientation info from the header of volumes loaded with the -dti option. Hopefully it's fixed now!

Hello experts,
I have come across what I think could be an inconsistency with how freeview interprets and/or displays dti data as vectors. Specifically, the x component seems to be inverted in freeview from freesurfer-Darwin-lion-stable-pub-v5.3.0 as compared to fslview (version 509) AND freeview from freesurfer-Darwin-OSX-stable-v6-beta-20161116-5037eae.
Is this a known issue with a patch available? Any insight would be greatly appreciated.
Thanks,
Doug
