text: user17033: I am at this point in the GitHub tutorial: https://github.com/DerrickWood/kraken2/blob/master/docs/MANUAL.markdown#standard-kraken-2-database
  It says to create the standard Kraken database, I use the following command:
  kraken2-build --standard --db $DBNAME
  
  It then says to change $DBNAME with the preferred database name/location. Is this something that I need to download on my own? Where can I find it, and how do I do it?
  To provide context, I want to use Kraken2 to identify whether or not there is the presence of MCPyV in a tumor sample.

  kraken2-build --standard --db /media/ip80/externalDrive/kraken_indexes/betterThanGenbank
