Genome polarisation for admixture genomics This is to announce the first official release of *diempy*, a python package for fast and reference-free genome polarisation. The package is available on PyPi and easily installed using pip. A brief introduction, installation instructions, and API documentation are available on *read the docs*: https://diempy.readthedocs.io/en/latest/intro.html We provide an extensive and interactive tutorial that showcases all the features of *diempy* and outlines the basic workflow in Jupyter Notebook: https://github.com/DerekSetter/tutorial-DiemPy. We recommend starting there. The code for *diempy* is available open-source on gitHub: https://github.com/Studenecivb/diemPy Please, DO NOT REPLY to this email (of course).
