Release

Dear Biopythoneers, Source distributions and Windows installers for Biopython 1.65 are now available from the downloads page on the official Biopython website and from the Python Package Index (PyPI). This release of Biopython supports Python 2.6, 2.7, 3.3 and 3.4. It is also tested on PyPy 2.0 to 2.4, PyPy3 version 2,4, and Jython 2.7b2. The most visible change is that the Biopython sequence objects now use string comparison, rather than Python’s object comparison. [Read More]

Source distributions and Windows installers for Biopython 1.62 are now available from the downloads page on the official Biopython website and ( soon) from the Python Package Index (PyPI). Python support This is our first release of Biopython which officially supports Python 3. Specifically, this is supported under Python 3.3. Older versions of Python 3 may still work albeit with some issues, but are not supported. We still fully support Python 2. [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).

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]

The Biopython community is pleased to announce the release of Biopython 1.57. Source distributions and Windows installers are available from the downloads page on the Biopython website and from the Python Package Index. Bio.SeqIO now includes an index_db() function which extends the existing indexing functionality to allow indexing many files, and more importantly this keeps the index on disk in a simple SQLite3 database rather than in memory in a Python dictionary.

The Biopython team is pleased to release Biopython 1.56, almost exactly three months after our last stable release ( Biopython 1.55). The Bio.SeqIO module has been updated to support protein EMBL files (used for the patents database), IMGT files (a variant of the EMBL file format, with help from Uri Laserson), and UniProt XML files (thanks to Andrea Pierleoni). Also the SeqFeature object gained some new methods, and the Bio.Seq translation function can now be used with an arbitrary genetic code. [Read More]

The Biopython team is proud to announce Biopython 1.54, a new stable release of the Biopython library. Biopython 1.54 comes five months after our last release and brings new features, tweaks to some established functions and the usual collection of bug fixes. This is the first stable release to feature the new Bio.Phylo module which can be used to read, write and take data from phylogenetic trees in Newick, Nexus and PhyloXML formats. [Read More]
