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> (will rewrite script to create automatic output file)
      2. To alignmuscle Usage: > muscle -in <FASTA_File> -out <OUTPUTfilename.aln> -clwstrict Phylogeny; Tree display (R commands)

  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)
