Well, doing some sequencing and genome assembly and analysis for my EVE 198 class and thought I would post notes here.

Step 1. Make Illumina libraries and generate sequence data.  Ideally PE but not 100% necessary

Step 2. Process data.

Raw data is here

• https://www.dropbox.com/s/tryj7acf2lmoy4c/NexteraPcrFree_451.r1.fastq
• https://www.dropbox.com/s/t8rw69uiyrk9qnm/NexteraPcrFree_451.r2.fastq

Some test data for blast and trees

Step 3. Make 1st pass assembly using A5

Download an install

• download from http://code.google.com/p/ngopt/
• downloaded Mac version and installed http://code.google.com/p/ngopt/downloads/list
• for those using Windows machines there are a few options
  • emulate MAC or Linux environment on your PC
  • use an alternative assembly method

Running A5 on test data

• ran test on phiX174 sample data
• command: ./a5_pipeline.pl ../example/phiX_p1.fastq ../example/phiX_p2.fastq test
• worked: produced lots of files at least
• See original Sanger paper as a side note http://www.nature.com/nature/journal/v265/n5596/abs/265687a0.html
• Also see http://www.ncbi.nlm.nih.gov/nuccore/9626372?report=graph

Ran on Ruthia data

• ./a5_pipeline.pl /Volumes/Phylogenomics3/Sequencing/Eisenia/NexteraPcrFree_451.r1.fastq /Volumes/Phylogenomics3/Sequencing/Eisenia/NexteraPcrFree_451.r2.fastq Ruthia
• Ruthia contigs (if for some reason data does not load try here)
• Also here is a .sam file that has the mapping of the reads to the contigs
• aligning to reference genome
• progressive Mauve
• http://nbc11.biologie.uni-kl.de/framed/left/menu/auto/right/contig_aligner/

Step 4 View Results

• downloaded Tablet and Installed
• http://bioinf.scri.ac.uk/tablet/
• http://bioinf.scri.ac.uk/tablet/download.shtml
• run installer
• open program
• import phix test data
  • test.raw1.sub.pe.sam
  •  test.final.scaffolds.fasta
• play around
• should be able to do the same with the Ruthia contigs and .sam file linked above

Step 5 Gene finding

• PhiX test
• Practice on the web: Use NCBI ORF Finder
• Phix Scaffold (test.final.scaffolds.fasta)
• >scaffold1.1|size5470

I am an evolutionary biologist and a Professor at U. C. Davis. (see my lab site here). My research focuses on the origin of novelty (how new processes and functions originate). To study this I focus on sequencing and analyzing genomes of organisms, especially microbes and using phylogenomic analysis View all posts by Jonathan Eisen
