Yes, it's all sourced correctly. The output after sourcing:

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?
