Thirdkind: displaying phylogenetic encounters beyond 2-level reconciliation

Abstract Motivation Reconciliation between a host and its symbiont phylogenies or between a species and a gene phylogenies is a prevalent approach in evolution, however no simple generic tool (i.e. virtually usable by all reconciliation software, from host/symbiont to species/gene comparisons) is available to visualize reconciliation results. Moreover there is no tool to visualize 3-levels reconciliations, i.e. to visualize 2 nested reconciliations as for example in a host/symbiont/gene complex. Results Thirdkind is a light and easy to install command line software producing svg files displaying reconciliations, including 3-levels reconciliations. It takes a standard format recPhyloXML as input, and is thus usable with most reconciliation software. Availability and implementation https://github.com/simonpenel/thirdkind/wiki.
