Tree editing interactive screen of gmap.pl. The phylogenetic tree file (from the included dataset) is displayed as a cladogram, allowing the user to make the necessary labeling. This screen shows various information (from left to right), such as the total number of nodes modified or affected, the total number of nodes labeled, the current selected display mode, which enables alternative display of phylogenetic tree information (i.e., bootstraps, branch lengths, both or none) and the cladogram branch length. The interactive commands for labeling and other operations can be consulted through an interactive help menu, by entering the “?” character in this screen or through the command-line option “--help” (as in gmap.pl --help), which will print the help into a specific text file in current directory (see Additional file 2: Figures S1 and S2)
