Nexus Mode

 

 

 

 

 

 

 

 

 

 

The Nexus Illustrator is designed to illustrate taxa, characters, and character states in a standard nexus file. It also includes options to aid in the identification of the included taxa. In the standard view, which is the default Nexus Mode that is shown below, the taxon names are on the left hand column, the character and character state names are presented in top row, and the internal cells of the matrix contain illustrations of the character states for each taxon. The example shown below (Fig. 2) has about 49 species of Alabagrus (Hymenoptera: Braconidae: Agathidinae) and 871 high resolution jpeg images. There are only a small handful of "characters" presented to show how a Nexus file may be illustrated. The corresponding Nexus file is presented below (Fig. 1) immediately above the Nexus Illustrator (Fig. 2). These two files interact dynamically such that when changes in coding are made in the Nexus file they appear in Nexus Illustrator as well. The HymATOL project is currently looking at this software as our method of illustrating, or virtually vouchering, our morphological matrix for the skeletal, or core taxa, for our study of the phylogeny of the Hymenoptera.

Soon we expect to integrate this initiative with MorphBank, an open web repository of images serving the biological research community. Images deposited on MorphBank could display dynamically in Nexus Illustrator.
