GCSpeciesSorter:

GCSpeciesSorter is a binary classification package for distinguishing between two or more species based on the GC contents of their DNA or RNA sequences. It includes source code in Python and is released under the GNU General Public License (GPL). Beyond unpacking, there is no special installation step necessary. Python, LIBSVM9 and/or C4.5, and optionally, BLAST are needed to run the scripts. A README file in the package provides more details about running the scripts. The package includes all the input files mentioned in this paper to use as a tutorial, including test sequence files and BLAST database files.

You can read the paper Distinguishing Species Using GC Contents in Mixed DNA or RNA Sequences for more information.
