Customized the reference database

[Chao-Jui Chang]

Dear PICRUSt2 team

I have a question about the version of the reference database used by PICRUSt2

Although I can access the reference file on the picrust2/default_files in the GitHub

one question is what is the version of these files (namely the released date of this file (eg., ko_info.tsv.gz, ec_level4_info.tsv.gz, metacyc_pathways_info.txt.gz))

I think these files are from KEGG, the International Union of Biochemistry and Molecular Biology, and MetaCyc

however, I can not find  the information about the version of these files so far

I think these databases are not the newest version

is it possible to use a customized database for example the New KEGG pathways database, I access

Sincerely,

Chao-Jui

Hi there Chao-Jui,

I fairly recently added a new FAQ response about this to the PICRUSt2 wiki: https://github.com/picrust/picrust2/wiki/Frequently-Asked-Questions#how-were-the-annotations-used-for-picrust2-predictions-generated-are-they-updated

So unfortunately I don't actually know the version that was used for these (and it may well differ for different genomes). I do hope to get around to testing with the new annotations that I'm creating soon, and I'll let the community know here when that happens!

Best wishes,

Robyn
