Projects

  1. Build a local genome database
    1. Database schema:
      1. "genome": genome_id, strain_name, ncbi_taxid
      2. "orf": genome_id, locus_tag, start, stop, strand, genome_name, product_name
      3. "orth_orf": orth_orf_id, locus_name, genome_id, orth_class
    2. Parsing scripts
      1. Rayees Parsing code, requires that you remove columns 9-27 using bash command: cut -c 1-8 (I will write a bash script that does this and runs the program) https://www.dropbox.com/s/lpxxbkxeyw7frrn/parser.pl
    3. Database loading scripts
  2. Molecular Evolution of flagellum genes
    1. Download orthologs
    2. Reconstruct phylogenetic tree
    3. Run PAML tests

Update: June 18, 2013

  1. Material and Methods
    1. Protein ortholog data: fleN, fleQ, flhF
    2. Protocol:
      1. Fasta headers are too long for tree, run: rename.pl to shorten names usage: >rename.pl FASTA file > OUTPUTfilename.fas editing/rule (script name?); Alignment (tool and command); Phylogeny; Tree display (R commands)
Gene Alignment Tree Notes
fleN fleN pep alignment Flen.png Conserved Domain
fleQ fleQ pep alignment Fleq.png Conserved Domain
flhf flhF pep alignment Flhf.png Conserved Domain

  1. Finish parsing the genome files to upload the "orf" table (Raymond & Rayees)
    1. Rayees Parsed genome files: https://www.dropbox.com/sh/k0zktvvmv39op9i/1zBercEky8
  2. Parsing the ortholog file to upload the "orth_orf" table (Raymond)
  3. Identify and download fleN, fleQ, and flhF orthologs & align them (Rayees)
