Open steamsn opened 1 year ago

steamsn commented 1 year ago

Hello, download the prebuilt database (https://benlangmead.github.io/aws-indexes/k2), but when running, an error is reported, how to solve it? "kraken2: database ("./database/db") does not contain necessary file taxo.k2d" But it exists in the folder.

Can you post your folder structure?

Thanks. this issue is caused by the lack of gcc in wsl-ubuntu.

I encountered this error when calling the database from a directory other than my working directory. When I moved the database to my working directory, this problem resolved itself.
