External Email - Use Caution
The system you are running freesurfer 5.3 on likely uses older system libraries that are incompatible with reading current 7.X licenses. Or 7.X licenses use different (newer) encryption libraries found only on more recent linux systems. So a license file you download now is not expected to work on a system where 5.3 runs with its original license. If you still need to run 5.3 (released in 2013/2014), then you should run it on the system where it works using its original license from that time period. If that system is not available, then you could try hosting a CentOS virtual machine with Freesurfer 5.3 installed on the Linux system where you run 7.4.1. You can download a compressed archive of a VirtualBox CentOS disk image with Freesurfer 5.3 installed from,https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/5.3.0/freesurfer-Virt... You would need to install the VirtualBox application on your current Linux machine to run it. We discourage posting license files to public lists. - R.

I used freesurfer 7.4.1 for the recon-all command, not knowing I needed a different version for the rest of the processing. I used a license that I downloaded month ago and it worked perfectly for freesurfer 7.4.1 but this license doesn’t work with freesurfer 5.3. I downloaded a new license and it didn’t work. I tried changing the permission of access on the license.txt, checked the license key, set properly all environments as FREESURFER_HOME and SUBJECTS_DIR, etc and everything is in order but it still doesn’t work. I even redownloaded another license and tried again but I still encounter the same error:
ERROR: Invalid Freesurfer license key found in license file /usr/local/freesurfer/license.txt
If you are outside the NMR-Martino Center, go to https://surfer.nmr.harvard.edu%C2%A0to get a valid license file (it’s free). If you are inside the NMR-Martinos Center, make sure to osurce the standard environment.
Attached to this email you can have a look over the license I have. Thank you in advance for your reply. Best regards, Yéléna <license.txt>_______________________________________________Freesurfer mailing listFreesurfer@nmr.mgh.harvard.eduhttps://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
