 From repository:
-> chromatic_tda is a package for computing six-packs of persistent diagrams of colored point clouds, such as cells on a tissue slide with an information about their type or 3D stucture of a material composed of different atoms. The six-pack is a topological summary of capturing many aspects of how the different types of point mingle. It consists of kernel, domain, image, codomain, cokernel and relative persistence diagrams.

 > The main purpose of the code is to provide implementation to experiment with chromatic topological data analysis. Although not completely naive, many aspects of the code can be optimised, especially if only part of the infomration from the six-packs turns out to be interesting in a given application.
