Hello all, I’m very pleased and excited to announce that the Open Bioinformatics Foundation has selected 5 very capable students to work on OBF projects this summer as part of the Google Summer of Code (GSoC) program. The accepted students, their projects, and their mentors (in alphabetical order): Wibowo Arindrarto: SearchIO Implementation in Biopython mentored by Peter Cock Lenna Peterson: Diff My DNA: Development of a Genomic Variant Toolkit for Biopython [Read More]

Applications due 19:00 UTC, April 6, 2012. /wiki/Google_Summer_of_Code The Open Bioinformatics Foundation (OBF) Summer of Code program provides a unique opportunity for undergraduate, masters, and PhD students to obtain hands-on experience writing and extending open-source software for bioinformatics under the mentorship of experienced developers from around the world. The program is the participation of the Open Bioinformatics Foundation (OBF) as a mentoring organization in the Google Summer of Code (GSoC). [Read More]

Google announced today that the Open Bioinformatics Foundation (OBF) has been accepted as a mentoring organization for Google Summer of Code 2012! Google Summer of Code (GSoC) is a Google-sponsored student internship program for open-source projects, open to students from around the world (not just US residents). Students are paid a $5000 USD stipend to work as a developer on an open-source project for the summer. For more on GSoC, see the GSoC 2012 FAQ. [Read More]

I’ve just finished writing up an example for the Biopython Tutorial of the new GenomeDiagram functionality added in Biopython 1.59. You can now control the start and end points of individual tracks, and you can add cross-links between regions of different tracks, as shown here: This example attempts a simplified reproduction of Figure 6 in Proux et al. (2002), and shows three related phage genomes one above the other. Different classes of genes have been given different colors, while the strength of the red shaded cross-links indicates the percentage identity of the linked genes. [Read More]

Source distributions and Windows installers for Biopython 1.59 are now available from the downloads page on the Biopython website and from the Python Package Index (PyPI). Platforms/Deployment We currently support Python 2.5, 2.6 and 2.7 and also test under Jython 2.5 (which does not cover NumPy). Please note that this release will not work on Python 2.4 Most functionality is also working under Python 3.1 and 3.2 (including modules using NumPy), and under PyPy (excluding our NumPy dependencies).

One of the new things coming in Biopython 1.59 is improved chromosome diagrams, something you may have seen via Twitter. I’ve just been updating the Biopython Tutorial (current version here, PDF) to include an example drawing this: Here’s a PDF version too. This example just parses the Arabidopsis thaliana GenBank files to get the chromosome lengths and the tRNA gene placements. There are so many tRNA on the forward strand of Chr I that their labels are forced to overlap. [Read More]

Source distributions and Windows installers for Biopython 1.58 are available from the downloads page on the Biopython website and from the Python Package Index (PyPI). A new interface and parsers for the PAML (Phylogenetic Analysis by Maximum Likelihood) package of programs, supporting codeml, baseml and yn00 as well as a Python re-implementation of chi2 was added as the Bio.Phylo.PAML module. Bio.SeqIO now includes read and write support for the SeqXML, a simple XML format offering basic annotation support. [Read More]

BioPerl 1.6.9 is now available in CPAN. In this release: Refactored Bio::Species/Bio::Tree New SeqIO modules (gbxml, msout, mbsout) Updates for perl 5.12 Bio::Assembly support for SAM/BAM, Newbler, ace output Bio::DB::SeqFeature updates PAML updated to work with v. 4.4d lots of various bug fixes, around 50 Just to note, this is the first release after we reworked the Build.PL system, so we will probably hit a few speed bumps along the way.
