Thank you very much for replying! 

We use just SLURM. The error file in the scripts folder reads:

/var/lib/slurm-llnl/slurmd/job177034/slurm_script: 2: /var/lib/slurm-llnl/slurmd/job177034/slurm_script: module: not found
slurmstepd: *** JOB 177034 ON small29 CANCELLED AT 2018-02-21T10:05:09 *** 


As I understand it, module is used to set up the enviroment, here Matlab, but Matlab is already set up. 

However, any help would really be appreciated. 

Best
