Hello--

Good morning. Thank you very much for your email.

Yes we have the license file. When we didn't have the license file, we would get an error about missing license file.

If you are outside the NMR-Martinos Center,

go to http://surfer.nmr.mgh.harvard.edu to

get a valid license file (it's free).

If you are inside the NMR-Martinos Center,

make sure to source the standard environment.

Ok, will you confirm Ubuntu 18 can not run Freesurfer 4?

Thanks,

Paulo

Hello Paulo,
What is the location of the freesurfer license file (?), i.e., I would make sure the freesurfer license file is under $FREESURFER_HOME and then see if you get different results running the command.

Even with the license file though, I’m not sure all the Freesurfer 4 binaries will run on Ubuntu 18

Hello FreeSurfer Developers,

I am helping a researcher in my department run FreeSurfer on a new computer.. They insist that it should run on FreeSurfer 4.5 because their old system ran that version. Is the following possible? We can run FreeSurfer 6.0 fine, but they say there are differences between the versions.
1) FreeSurfer version: freesurfer-Linux-centos4_x86_64-stable-pub-v4.5.0-full
2) Platform: Ubuntu 18.04.1 LTS
3) uname -a: Linux clps-pb1 4..15.0-64-generic #73-Ubuntu SMP Thu Sep 12 13:16:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
