Hi,  
I have been trying to use biobakery workflow container to analyze the humann3 whole metagenome shortgun seq processed output. The container I pulled is by:  
$ singularity pull docker://biobakery/workflows:3.0.0.a.7

When I ran it, it gave me error:  
$wf=/uufs/chpc.utah.edu/common/home/hcibcore/u0762203/microbiomeTestPipe/containers/workflows\_3.0.0.a.7.sif  
$ singularity exec $wf biobakery\_workflows stats -h  
Traceback (most recent call last):  
File “/usr/local/bin/stats.py”, line 44, in   
description=“A workflow for stats on wmgx and 16s data sets”)  
File “/usr/local/lib/python3.6/dist-packages/anadama2/workflow.py”, line 120, in **init**  
self.document=PweaveDocument()

self.vars=self.get\_vars()  
File “/usr/local/lib/python3.6/dist-packages/anadama2/document.py”, line 325, in get\_vars  
vars = pickle.load(open(pickle\_file[0],“rb”))  
\_pickle.UnpicklingError: pickle data was truncated

I am new to biobakery workflow, so any help will be greatly appreciated! Thank you!

according to this post([Biobakery Workflows: Errors with downloading database, "unpicking error", “topological\_sort()" error, and "Unable to find Trimmomatic" error](https://forum.biobakery.org/t/biobakery-workflows-errors-with-downloading-database-unpicking-error-topological-sort-error-and-unable-to-find-trimmomatic-error/1823)), I need to first install the databases before running the Docker container. I did install all the databases of humann3 somewhere else on the HPC server, but how could I let the Docker container know it…?
