Could anyone help me with a dropbox or any other link to download UniRef90\_annotated\_v201901b\_full database? I am trying from [Index of /databases/HUMAnN](http://cmprod1.cibio.unitn.it/databases/HUMAnN/) but unable to do so. Previously, I downloaded uniref90\_annotated\_v201901.tar.gz through _humann\_databases --download uniref uniref90\_diamond $INSTALL\_LOCATION_ but facing version related issue. I am using humann v3.0.0. Any help is much appreciated. ---

Can you post the error message you are seeing? Using `humann_databases` is still the preferred way to fetch the databases (we don’t have them mirrored in Dropbox, unless someone else has done that unofficially). ---

Hi Eric, @franzosa I am using humann v3.0.0. I have downloaded Chocophlan and Uniref90 full databases running _humann\_databases --download chocophlan full $INSTALL\_LOCATION_ and _humann\_databases --download uniref uniref90\_diamond $INSTALL\_LOCATION_ respectively. I have paired-end data, and converted it to a single file through cat. when I ran _humann --input SLG\_cat.fastq --output humann3\_output_ I am getting an error message **CRITICAL ERROR: The directory provided for ChocoPhlAn contains files ( full\_chocophlan.v296\_201901.tar.gz ) that are not of the expected version. Please install the latest version of the database: 201901b**. I followed this link [Difficulty downloading databases in humann3 - #24 by sagunmaharjann](https://forum.biobakery.org/t/difficulty-downloading-databases-in-humann3/1343/24) and downloaded full\_chocophlan.v296\_201901b.tar.gz and configured the path. when I reran _humann --input SLG\_cat.fastq --output humann3\_output_ I got another error **CRITICAL ERROR: The directory provided for ChocoPhlAn does not contain files of the expected format (ie ‘^[g\_\_][s\_\_]’).** I am unable to detect where I’m doing wrong. Pls help me out. ![Screenshot from 2021-08-07 16-23-28](https://canada1.discourse-cdn.com/flex027/uploads/biobakery/original/1X/a3fe3407e1a2cc06c9a1de1597f1e141a3d3dec7.png) ---

It looks like you have the original zipped archive (full\_chocophlan.v296\_201901.tar.gz) in the folder with the unzipped contents. HUMAnN is complaining because that file doesn’t look like a pangenome. If you move that file out of the unzipped pangenomes folder it should solve this problem. ---

Thanks Eric, It works!
