Hi there,

I’m having trouble downloading the biobakery databases. In this example, I’m using conda and generating the environment in the normal way. Here is the command I use and the error I receive. Note, I replace the actual directory path with a generic “$WKDIR” for discretion. I’ve tried downloading the databases in several ways, without success. Is anyone able to provide guidance?

Command:

biobakery\_workflows\_databases --install wmgx --location $WKDIR

Output:

Installing humann utility mapping database  
Creating directory to install database: $WKDIR/humann  
Creating subdirectory to install database: $WKDIR/humann/utility\_mapping

CRITICAL ERROR: Unable to download and extract from URL: [http://huttenhower.sph.harvard.edu/humann\_data/full\_mapping\_v201901b.tar.gz](http://huttenhower.sph.harvard.edu/humann_data/full_mapping_v201901b.tar.gz)

Thanks in advance, let me know if you need more information.
