Robinson-Foulds distances between trees of the Hong Kong dataset. The intensity of the squares corresponds to the degree of distance. Distances range from 0 to 6, representing the number of bipartitions present in one tree but not in the other. Some trees have the same topology (NP and PB1, NS and PB2) whereas the NA tree seems to be most distant to the other trees (distance of 6).
