Dear Daniel,
It seems that link to the last version of the file that maps NCBI-nr accessions to taxonomic and functional classes (NCBI, GTDB, EC, eggNOG, InterPro2GO, SEED), megan-map-Jan2021.db.zip, is broken because it returns a “File not found” error when I try to download it.
Could you please provide the file for download?
Thank you very much!
Alex
