  "Description": "The popular population genetic software 'Treemix' by\n'Pickrell and Pritchard' (2012)\n<DOI:10.1371/journal.pgen.1002967> estimates the number of\nmigration edges on a population tree. However, it can be\ndifficult to determine the number of migration edges to\ninclude. Previously, it was customary to stop adding migration\nedges when 99.8% of variation in the data was explained, but\n'OptM' automates this process using an ad hoc statistic based\non the second-order rate of change in the log likelihood.\n'OptM' also has added functionality for various threshold\nmodeling to compare with the ad hoc statistic.",
