Gaps contain certain revolutionary information for phylogenetic analyses. This information should be taken into account in order to estimate the phylogenetic relationship accurately. Among the most widely used gap coding methods, seven of them are discussed. An example is given to illustrate how these methods work. In addition, some empirical suggestions concerning how to use them in some existing phylogenetic procedures are also given to help researchers select these methods. However, all of them have both advantages and disadvantages, new gap coding methods are needed to code gaps better in phylogenetic analyses.
