I have a morphological character matrix previously used in a cladistic analysis. I now would like to use this data set to generate taxonomic descriptions and identification keys. It turned out this is not really a straightforward process. The matrix was stored in Winclada. I was able to export a nexus file of the data set. I would to use DELTA to edit this data set. DELTA does not read a nexus file. After some research I was able to import the nexus file into DELTA. See the procedure described below.
Download NDE (Nexus Data Editor) here (runs on Windows 7, but did not run on my Windows 8 desktop) written by Rod Page.
Open nexus file in NDE and go to 'Export' (under 'File'). Select 'DELTA' under Export. A pop-up window appears. Select directory/folder to export the DELTA format 'directive files' (there are four of them). Put these files in a new folder.
In DELTA select 'Import directives...' (under 'File'). Copy/paste the folder directory (folder path) where you just saved the DELTA format directive files. A new window pops up and click 'OK'. Your data set should now appear in DELTA Editor.
Also see discussions at the DELTA mail-list about format conversion: [Converting Nexus to DELTA] [Nexus vs DELTA files] [Delta, Lucid and the Nexus data editor] [Nexus data editor for Windows] [add different sets of attributes to items]
