Description

xASL_fsl_SetFSLdir finds the FSL directory and defines it, for further use in e.g., FSL BET or TopUp. This included WSL1 — which uses a path inside the WSL software — but didn't yet include WSL2 — which mounts a separate file as network shared disk. This is now added for Ubuntu18.04 and Ubuntue20.04, though this may be improved in the future for other Ubuntu distributions.

How to test

Tested with macOS, Linux, and with Windows WSL2. Needs to be tested with Windows WSL1 yet.
Can be tested by initializing ExploreASL and running xASL_fsl_SetFSLdir([],1) which should automatically detect and output the FSL dir (if installed). xASL_fsl_SetFSLdir should work if FSL is defined in the OS system.
