I am trying to download databases for humann3, using the provided ‘humann_databases’ command to do so. Using this command starts the download as expected, only to fail at about 5~7%.
command used: humann_databases --download uniref uniref90_diamond uniref_db/
error generated: CRITICAL ERROR: Unable to download and extract from URL: http://huttenhower.sph.harvard.edu/humann2_data/uniprot/uniref_annotated/uniref50_annotated_v201901.tar.gz
This error did not give me much to work with, so I started with some troubleshooting of my own. I have tried many of the easy solutions that come to mind: I run humann3 from an environment containing only humann3, python 3.7 and their dependencies; I have tried to run it from two different linux systems (both with a stable connection, and full read and write rights); I have tried to download other databases (the demo database and chocophlan work just fine); finally I also tried to download the databases using wget which cuts off the download at about the same progress.
As I don’t understand what’s going wrong, I would like your help with downloading the uniref90 database.
