Biopython is a set of freely available tools for biological computation written by an international team of developers.
Biopython features include parsers for various Bioinformatics file formats (BLAST, Clustalw, FASTA, Genbank,…), access to online services (NCBI, Expasy,…), interfaces to common and not-so-common programs (Clustalw, DSSP, MSMS…), a standard sequence class, various clustering modules, a KD tree data structure etc. and even documentation.
Many of Biopython’s modules contain command line wrappers for commonly used tools, allowing these tools to be used from within Biopython. These wrappers include BLAST, Clustal, PhyML, EMBOSS and SAMtools.
- The ability to parse bioinformatics files into Python utilizable data structures, including support for the following formats:
- Blast output – both from standalone and WWW Blast.
- PubMed and Medline.
- ExPASy files, like Enzyme and Prosite.
- SCOP, including ‘dom’ and ‘lin’ files.
- Files in the supported formats can be iterated over record by record or indexed and accessed via a Dictionary interface.
- Code to deal with popular on-line bioinformatics destinations such as:
- NCBI – Blast, Entrez and PubMed services.
- ExPASy – Swiss-Prot and Prosite entries, as well as Prosite searches.
- Interfaces to common bioinformatics programs such as:
- Standalone Blast from NCBI.
- Clustalw alignment program.
- EMBOSS command line tools.
- A standard sequence class that deals with sequences, ids on sequences, and sequence features.
- Tools for performing common operations on sequences, such as translation, transcription and weight calculations.
- Code to perform classification of data using k Nearest Neighbors, Naive Bayes or Support Vector Machines.
- Code for dealing with alignments, including a standard way to create and deal with substitution matrices.
- Code making it easy to split up parallelizable tasks into separate processes.
- GUI-based programs to do basic sequence manipulations, translations, BLASTing, etc.
- Extensive documentation and help with using the modules, including this file, on-line wiki documentation, the web site, and the mailing list.
- Integration with BioSQL, a sequence database schema also supported by the BioPerl and BioJava projects.
