Conversion of multistate characters to sets of binary columns. On the left is the table used to encode each multistate character. If three character states are seen at a position the first three columns are used. There are five possible characters corresponding to the four DNA bases with a fifth character representing indels. On the right is the network constructed for three character states A, B and C connected by the virtual median '100' labelled with an asterisk.
