What is NDE?

NDE (NEXUS Data Editor) is a program to create and edit NEXUS format data files on computers running Microsoft Windows 95/NT 4.0. The main motivation behind my writing the program was to provide an easy to use data editor similar to that provided in the Macintosh program MacClade (note that NDE has none of the data or tree analysis features of MacClade). The NEXUS format is becoming more widely used on PCs now that DOS and Windows versions of PAUP* are available for testing.

In addition to a spreadsheet data editor, NDE makes it easy to fully annotate the data with both text and pictures, and to have lengthy descriptive character and character state names. This last feature avoids the constraint imposed by MacClade of character and state names being being limited to 32 characters. Hence cryptic phrases such as "ant. temp. marg." (anterior temporal margin) can be avoided. The ability to have lengthy character names, together with text comments, means that the data set can be largely self documenting. Indeed, if suitably constructed the character names and comments can be exported by the program directly into a file readable by a word processor, automating the production of character definitions for publication. NDE can also output HTML. Although designed as a NEXUS file editor, NDE also has limited support for other formats, including Hennig86 and DELTA.
