Project Goals

A Borrelia Phylogeny
  • Annotate and add newly sequenced Borrelia genomes to BorreliaBase
  • Build an informatics pipeline for gene prediction, ortholog calls, databasing, and synteny analysis

Protocol

Dependencies

Part 1. Fetch genome sequences and extract protein sequences

  • Note: These scripts are in "../../bio425/annotate-a-genome-pipeline". You may either make a copy to your home directory (recommended) or run directly from that directory by including the path
  • Commands:
./fetch-genome.pl <your_assigned_accession> # Expected output: "accession.gb"
./gb2pep.pl <accession.gb> # Expected output: "accession.pep"

Part 2. Predict orthologs with reciprocal BLAST

  • Note: Replace the "accession" in the following commands with your assigned accession number.
  • Commands:
makeblastdb -in accession.pep -parse_seqids # Prepare the new genome DB
blastp -query accession.pep -db ref.pep -outfmt '6 qseqid sseqid pident length qlen evalue' -evalue 1e-3 -out accession.fwd # Forward BLAST # customized outfmt 6
blastp -query ref.pep -db accession.pep -outfmt '6 qseqid sseqid pident length qlen evalue' -evalue 1e-3 -out accession.rev # Reverse BLAST
./check-reciprocal.pl <accession.fwd> <accession.rev> > accession.orthlogs 2> accession.not-orthologs # Identify orthologs

Part 3. Generate database tables

  • Note: Use your assigned genome_id in the table above as the argument for the "-g" option
./gb2table.pl -g <genome_id> -t <accession.gb> # Expected output: "accession.contig.txt"
./gb2table.pl -g <genome_id> -f <accession.gb> # Expected output: "accession.orf.txt"
