How to merge Refseq databases？ #836

Open smoothyly opened 6 months ago

smoothyly commented 6 months ago

The following is my code

kraken2-build --download-library bacteria --db bacteria kraken2-build --download-taxonomy --db bacteria kraken2-build --download-library plant --db bacteria kraken2-build --build --db bacteria --threads 48 I want merge bacteria and plant database,but I found the file size to be the same before and after the build b5e530b5f8b668d0918fd9afed059e1 So there's a way to merge the databases?

I followed the above code to build the database,but I found that building one library and two libraries get the same comparison results. Any help would be appreciated! @DerrickWood image

Are you running all the commands in the same folder?. Can you show the contents of the library/ folder?
