This directory contains files distributed concurrent with the manuscript "Geometric unmixing method for tumor phylogeny inference" by R. Schwartz and S. Shackney. The files provide Matlab .m source code for the major inference routines described in the manuscript. The following files are included in the release: Unmix.m: Routine for performing mixture type separation on a tumor sample. Phylogeny.m: Routine for using mixture type fractions to infer a phylogeny. Please refer to the paper for details on the implementation and explanation of the inputs and outputs.
