Generate Ribosomal Metadata:

Identifies, extracts, and taxonomically classifies 16S and 23S rRNA genes in genomes against SILVA

  • check if a new version of SILVA has been released. If so, download this and update the rna_silva.py script to point to the new SILVA data and to store results in a new directory (i.e., currently rna_silva_132).
  • see Update Silva
  • need to run for 16S, 23S, and 5S rRNA genes

Current silva version: 138.2

module load blast (optional)

Identifies, extracts, and taxonomically classifies 16S rRNA genes in genomes against the Living Tree Project (LTP)

  • check if a new version of LTP has been released. If so, download this and update the rna_ltp.py script to point to the new LTP data and to store results in a new directory (i.e., currently rna_ltp_132).
  • need to run for 16S

Current LTP version: 08_2023
Current SSU version: 138.2
