WebJul 31, 2014 · The Fitch-Margoliash algorithm applies a least-squares method to estimate per branch length (in our case, equivalent to the genome multiplicity) based on all pairwise distances between the genomes in comparison. The procedure was pipelined by an in-house Python script with manual inspections at various intermediate stages.
