Permission issues

[nuest]

Hi! I cannot execute the workflow with the provided commands:

daniel@gin-nuest:~$ docker exec -ti -u workflow:workflow soybean bash
workflow@1d974218c269:~$ whoami
workflow
workflow@1d974218c269:~$ cd soykb/
workflow@1d974218c269:~/soykb$ ls     
AutoADAG.py   README.md  inputs-fastq.txt       inputs-ref.txt  workflow-generator
AutoADAG.pyc  conf       inputs-fastq.txt.orig  software        wrappers
workflow@1d974218c269:~/soykb$ ./workflow-generator --exec-env distributed
bash: ./workflow-generator: Permission denied
workflow@1d974218c269:~/soykb$ 

There is no local user "workflow" on my machine, so "-u workflow" should suffice?

The file workflow-generator is owned by root:

workflow@1d974218c269:~/soykb$ ll
