External Email - Use Caution        

Hello all.

I am attempting to run recon-all in a docker container.  I have a set of 
commands to set up the system, and on my local machine (Ubuntu) it works 
fine.  However on the docker container (also Ubuntu) I get

nu_correct: Command not found.

I imagine there is some software that is required that I haven't 
installed on the container image - does anyone have any idea what it 
might be?

1. I have run these commands:

source /usr/local/freesurfer/SetUpFreeSurfer.sh
export 
PATH=/usr/local/freesurfer/bin:PATH=/usr/local/freesurfer/mni/bin:$PATH

2. I have set FREESURFER_HOME

Attached at the end is some output from both failing and successful runs.

3. nu_correct exists in freesurfer/mni/bin

4. Perl is present and correct on both systems.

Thank you in advance,
Ian
