External Email - Use Caution

 Since the last release of freesurfer 5.X in 2014, the encryption libraries on linux systems have changed such that the licenses downloaded for the current 7.X releases,https://surfer.nmr.mgh.harvard.edu/fswiki/rel7downloads- cannot work with 5.X. If you were previously using 5.X on an old linux system, then you could run it with the license file that worked for you on that system in a container or VM running whatever that OS was - hosted on a current version of Linux like Rocky8, Ubuntu 22, etc. Otherwise, I suggest you download and install the 7.4.1 release via the link above.  The license file you downloaded should work with that. - R.

However, when I try to run the example: mri_convert sample-001.mgz sample-001.nii.gz I get the following error: ERROR: Invalid FreeSurfer license key found in license file /home/john/freesurfer/license.txt I'm not sure what to do here as I have the license file in the correct place and thought that I had obtained it correctly.
