mv Question during kraken2-build (building database)

Question

[10mz1]

Hello all,

I'd downloaded and installed Karken2 locally on WSL Ubuntu. After install, I build a standard database with the command:

kraken2-build --standard --db databasename

here is the out:

mv: replace 'assembly_summary.txt', overriding mode 0555 (r-xr-xr-x)?

Note the question at the end.. This took all night to run and so I don't want to accidentally overwrite the main 172 Gbp of 16s sequences that have already been properly processed and complexity masked, what is this asking? What should I answer? Anything I should know before trying to determine taxonomy via 16S on my assembled fastqs of shotgun metagenome data?

Answer 1

To be safe. You can open a new terminal, navigate to the directory where this is running, save a copy of the existing assembly_summary.txt in that folder with a different name (cp assembly.txt assembly.txt.SAVE) and then say y to the question above to let the process finish.

thank you so much.
