Hi Satra

we did originally consider tracking usage in that way, but it seemed invasive and a bit creepy to have FreeSurfer keeping track of what you were up to and reporting back to us, so ultimately we decided not to

hi nick,
i really like pedro's idea of tracking through instance tracking as opposed
to licenses. on a separate project we are setting up the ability to pull up
as many instances as necessary and install whatever software environment
that's needed to run your analysis. we'll try to ensure that each person has
a license file in their "folder" that we can pull.

however given the current licensing of freesurfer, one can easily remove the
license components. that's why i feel the instance tracking is painless and
provides you with a better estimate of the number of times freesurfer is
run. as an example, at mit we have a single license which everybody uses and
that's not a great way for you to track the number of projects or subjects
run through freesurfer.

cheers,

      Long term, after we put together an 'official' instance of the
      AMI with
      scripts (which might well be an instance that Pedro Paulo
      created) I
      think sftp'ing the .license file to each instance is the way to
      go.
      The .license file need only apply to the user (not each instance
      or
      run).
