I have been having an immense amount of trouble being able to download the full_chocophlan.v201901_v31.tar.gz database for humann3. Everything else has gone well, but every time I use the command;
humann_databases --download chocophlan full path/to/directory
I eventually get an error. The thing is that the download actually does progress, but eventually it seems like the system gives up and i get the following error;
CRITICAL ERROR: Unable to download and extract from URL: http://huttenhower.sph.harvard.edu/humann_data/chocophlan/full_chocophlan.v201901_v31.tar.gz
I have tried downloading it directly from the http://huttenhower.sph.harvard.edu website, but that never works for me either. The download slows to a crawl and never progresses, for some reason.
Any help in how to obtain the database would be much appreciated.
