Dinopy (Dna INput and Output in PYthon) is a Python package that aims to simplify the development of bioinformatics applications by providing efficient facilities for DNA input and output. At the time of writing, there is no library for I/O of DNA specific files available which makes full use of the potential of Cython. Dinopy exports Cython level API bindings which can be used by other Cython applications for increased speedup.
We preseted a poster about dinopy at the GCB 2015.
