Hi,  
I have manually downloaded the “mpa\_v30\_CHOCOPhlAn\_201901.tar” file from Google Drive and run the command:

md5sum -c mpa\_v30\_CHOCOPhlAn\_201901.md5  
I get this message:  
mpa\_v30\_CHOCOPhlAn\_201901.tar: FAILED  
md5sum: WARNING: 1 computed checksum did NOT match

Are you able to retrieve the database from [Zenodo](https://zenodo.org/record/3957592)?

I tried to download the database and the checksum file from both the sources and in both case the checksum was OK.  
Can you try downloading them from a different machine and/or using `wget`/`curl`?

I have got the completed file by changing the network. Thanks for your help.
