Manual

an assembly tool for 16S ribosomal RNA recovery from metagenomic data

Dependencies:

Runbook:

Input: Paired-end metagenomic reads in FASTA format

Output: 16S genes recovered from metagenomic reads

Step 1: Identify 16S reads.

python filter_input.py paired_end_1.fasta paired_end_2.fasta output_dir cm_dir cm_to_use num_of_CPU

Example:

python filter_input.py sample_1.fasta sample_2.fasta filter_out cm ba 10

Step 2: Assemble 16S reads.

command: python reago.py filename.fasta -l READ_LENGTH

Optional parameters:

  • -o OVERLAP, default 0.7
  • -e ERROR_CORRECTION_THRESHOLD, default 0.05
  • -t TIP_SIZE, default 30
  • -b PATH_FINDING_PARAMETER, default 10

Example:

python reago.py filter_out/filtered.fasta sample_out -l 101

Note:

REAGO assumes the sequence names of a read pair to be XXXX.1 & XXXX.2. The only difference of their names is the last character.
