Custom Kraken2 db

Question

[valentinavan]

Hi,

I have created a custom kraken2 database but it produced an unmapped.txt file with a list of accession numbers.

1) How do I find the taxa that have been included in this created db?

2) Is there a way to overcome this issue? For example, is there another way to include these taxa?

3) A better alignment tool that allows the creation of custom db for metagenomic data

Thanks!
