Hello there

I am using `StrainPhlAn 3.0` to analyze metagenomic sequencing data to obtain the SNP results of several species. When i using `StrainPhlAn 3.0 workflow`, I need to clarify the species information, such as:

`extract_markers.py -c s__Ruminococcus_sp_5_1_39BFAA -o db_markers/`

I know that the metaphlan\_databases information is used in this analysis, but the database file is a .pkl file.

My question is, where can I get the species information stored in the metaphlan\_databases? This is more beneficial to my analysis

thanks
