Accession mapping file update in addition to meganDB file

User Questions

I know MEGAN V6 has switched over to the MeganMapDB mapping file, but I’m having some difficulties getting that to work with a blast outfmt 6 tabular file. I can get it working using the 2019 accession .abin file though. So I was wondering if you could provide an updated 2020 MEGAN accession .abin file?

My current setup won’t work with DIAMOND, which I’ve seen in other posts is recommended, and while I usually prefer to use the full blast format to be able to view alignments, my current blast files are too large (>100 gb) to put into MEGAN without running out of memory or having the program crash.

Thanks for your help!

Thanks, is this protein one though? Any chance you could do the same with the nucleotide accession mapping file, nucl_acc2tax?
