Programs supporting "Assessing differences between ancestral recombination graphs" by MK Kuhner and J Yamato dist_fns.py -- Python functions implementing ARG reading, ARG distance framework, and the RF and RFL metrics align.py -- Python functions implementing the Align metric inf_analyze.py -- Python program which computes the distances among ARGs inf_graph.py -- Python program which graphs the results of inf_analyze.py These programs rely on several distributed Python libraries, particularly the ETE2 tree library and the pyplot graphics library.
