Cannot download Chocophlan database

Microbial community profiling HUMAnN

Hi,

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.

Kind regards,
Imadh

Hi Imadh, Sorry to hear you are having issues with downloading the database from our server. Would you try one more time? Occasionally our server is under a bit of a load which can make downloads take longer. Hopefully when you try again it will all work out okay. If not, please post again.

Thank you,
Lauren

Hi Lauren,

I was able to download the database, but It does seem to have taken quite a few tries. May have been a timing issue, but At least it’s here.

Kind regards,

Hi Imadh, Glad to hear you got the database! Sorry it took so many tries. We will see what we can do on our end to make the downloads easier.

Thank you,
