Subject: [Freesurfer] Problem running recon-all

        External Email - Use Caution        

I recently installed freesurfer 7.4.1 on a Debian 12 system (using the Ubuntu 22 .tar.gz). When running recon-all, I get the following error:

-bash: /opt/freesurfer/freesurfer-7.4.1/bin/recon-all: cannot execute: required file not found

Paths are all set, and all scripts and executables have execute permissions.

What might be happening?
