Bio-Python

2/28/2013

0 Comments

 
Biopython is a set of freely available tools for biological computation (mainly bioinformatics calculations) written in Python by an international team of developers.

Here's a link with a good intro to the tools:
http://www.biocodershub.net/community/a-hitch-hikers-guide-to-biopython-sequences-and-alphabets/
  • Reading and writing common sequence (and other) file formats
  • Classes for the usual datatypes (sequences, alignments etc.)
  • Functions for the usual things you’d do with those datatypes (alignments, Blasting)
  • Facilities for data base queries
  • A very large etc., etc. There’s a lot in there.

9 Comments

 
Coursera.org offers 323 free online courses from major universities on a variety of subjects such as: Financial Engineering and Risk Management, AIDS, Introductory Human Physiology, Synapses, Neurons and Brains and more!

The Drug Discovery, Development & Commercialization course is offered by UC San Diego (Drs Williams S. Ettouati and Joseph D. Ma). Students will learn the process of drug discovery and development through specific examples of case studies to better understand the issues facing the challenges of delivering a new drug on the market. At the completion of this course you will be able to have a better understanding of how a small or large molecule becomes a pharmaceutical drug.

The Next Session starts Apr 19th 2013 for a 9 weeks long course.

Here is the syllabus and signup form.

Benchmark studies of NAMD and GROMACS

2/11/2013

0 Comments

 
We have recently performed benchmark studies of different systems (ranging from 200,000 atoms to 600,000 atoms) with and without GPU acceleration for the programs NAMD and GROMACS.

Larger systems seem to benefit from GPU acceleration with GROMACS; NAMD did not scale well using the GPU version.
For systems ~200,000 atoms Gromacs scales well up to 112 cores.

Interested in green chemistry?  Want to attend a conference in 2013?  If you are an international student/postdoc/lecturer living in the U.S. or abroad, you can apply for the Joseph Breen Fellowship by March 1, 2013.  The award covers up to $2,000 in travel expenses to qualified events. More info here.

Green chemistry in the context of the Breen Fellowship is defined as “the discovery and design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances.”

See here previous winners of the Breen Fellowship.

On the implementation of the AMBER force field in NAMD and GROMACS

2/5/2013

4 Comments

 
The AMBER force field ff99SB-ILDN has been recently shown to perform best among other force fields. See paper by the Shaw group: "Systematic Validation of Protein Force Fields against Experimental Data"

However, AMBER is not free and does not scale very well on over 256 cores, which means that it is best to run the NAMD or GROMACS codes using the AMBER force field if you are running on more than 256 cores or do not have Amber.

However, you should carefully read and implement the directions in this document for use with NAMD (NOT the UIUC one), which should give you identical energies if followed carefully.

For use with GROMACS follow these instructions: http://code.google.com/p/acpype/wiki/TestingAcpypeAmb2gmx or http://chemistry.csulb.edu/ffamber/
