ncbi-rrna-data 6.1.20120620-11 (arm64 binary) in ubuntu zesty

 This package contains some ribosomal RNA BLAST databases distributed
 as part of the NCBI C Toolkit that are too large and specialized to
 include in ncbi-data. Specifically, it contains the databases
 Combined16SrRNA_2-12-2008, LSURef_93.fasta, and SSURef_93.fasta,
 along with an alias file to facilitate searching all three of them in
 conjunction with the 16SCore database included in ncbi-data.
