population-structure 0.0.8

This version adds the version attribute to init.py so it can be accessed to check the package version.

Population Structure Package

A package for performing transformation between fst, coalescence, and migration matrices. The transformation between coalescence and migration is based on Wilkinson-Herbot's equations (2003). The transformation between fst and coalescence is based on the Slatkin's equations (2001).

Install package using pip

pip install population-structure
