HMMER (pfam)

Downloaded from the website. Compiled using:

env CFLAGS="-O3" ./configure --enable-threads --enable-lfs
-fast wasn't any better (seems to be for G5 only)

Had to drag and drop binaries to /usr/local/bin

 

Fink

Download and install fink as usual. Did install the latest X11 for Leopard linked from fink site.

install:
arb
bioperl
biopython
 
biopython has clustalw as a dependency. To get arb and clustalw to play nice, edit:
sw/fink/dists/unstable/main/finkinfo/sci/arb.info
and remove apropriate packages from "Conflicts:" line.
Then install final conflicting package with something like:
sudo dpkg --force-overwrite -i arb_20071207-1005_darwin-i386.deb

 

To get arb pt_server working:
ln -s /sw/bin /sw/share/arb/bin

edit /etc/hosts.
Change:
127.0.0.1    localhost
to
127.0.0.1    localhost    rocapws.ocean.washington.edu

Mac Pro

Setup the new mac pro.

GenomeDiagram

GenomeDiagram, Pretty much as described on webpages, but need to to libjpeg and freetype with fink. Several prerequesites, but straight forward.

REPK

Restriction Enzyme Picker Online, v.1.2

by Gabrielle Rocap and Eric Collins (rec3141.at.gmail.com)

REPK (Restriction Endonuclease Picker) finds sets of 4 commercially available restriction endonucleases which together uniquely differentiate designated sequence groups from a supplied FASTA format sequence file for use in T-RFLP. If you have a database of known sequences from an environment, this program could be useful to pick some enzymes that uniquely discriminate the different groups in your database.

Read the Manual

Enter your FASTA aligned sequences here:
(Here is an example input file: alignment5.txt)

Select the enzymes you would like to use: (REBASE Version 911)
(Hold down the [Control] key to deselect, or to select multiple enzymes)
At least two enzymes must be used.
NEB list of isoschizomers, the first (alphabetically) is shown below.
Type IIA enzymes (forward and reverse [+])

Enter any custom enzymes you would like to use in the following format (where ^ is the cut site):
NoCut [tab] zzz^zzz

Taxonomic rank: : which taxonomic group do you want separated out?
CHECK TAXONOMIC RANKS INSTEAD OF RUNNING REPK

Cutoff: : furthest apart two fragments can be in length and still be considered the same fragments

Min Fragment Lengths: : shortest acceptable fragment (must be greater than Cutoff)

Max Fragment Lengths: : longest acceptable fragment

Stringency: : an enzyme must distinguish MORE than this percent of groups to be acceptable

Max Missing Group Combinations: : the number of missing groups allowed

Max Matches Returned: : the most number of matches to print out (maximum 1000)



OPTIONAL -- Enter your RDP Classifier output file here -- OPTIONAL
(Here is an example input file: rdpdownload5.txt or generate your own here: RDP-Classifier)

Genome enabled ecology of marine microbes

 

The Thompson

Welcome to the home page of the Rocap lab, located in the School of Oceanography at the University of Washington. I am a marine microbial ecologist interested in the evolution and ecology of marine bacteria and phytoplankton. We use a variety of approaches in the lab; physiological (growth experiments and pigment analyses), molecular (quantitative PCR, sequencing and expression assays) and computational (phylogenetic analyses, comparative genomics). The multiple projects in the lab all address common questions: How does genetic diversity arise in marine microbial populations, how is it maintained, and how does it influence ecological success.

Our lab is part of the Center for Environmental Genomics, occupying 11,000 square feet of newly renovated lab space in the Benjamin Hall Interdisciplinary Research Building.
