We don't provide license.txt or .license files as part of any freesurfer distribution. We expect end users to receive and download their own license.txt file after completing the online registration...

OK, I've update the comments in the Dockerfile to point out the above.

I don't believe we can drop vtk5 support at this time.

Please re-post this to the freesurfer help list if you still have an issue, but closing the issue here.
