Brief overview of the capabilities of ERNA-3D

The following gives a summary in note form of the individual properties of
ERNA-3D:

* Easy-to-operate graphic user interface

* Creation of complex atomic structures

* Ability to "pull" atomic structures in a realistic manner

* Automatic docking of intra- and interhelical single strands

* Interactive alteration of Bond Angles and Dihedral Angles

* Functions to move, add, remove and connect single atoms

* Simple manipulation of helices and clusters

* Reading and writing of PDB files (all records)

* Extremely rapid reading and writing of atom lists (memory dump)

* Simple calculation of distances

* Detailed information about the contents of internal lists

* Creation of six different types of representations

* Reading and writing of polygon data files

* Extremely rapid reading and writing of polygon lists (memory dum

* Loading of MOVIE.BYU data files

* Direct generation of contours from electron density data

* Real time rendering of transparent contours (rapid polygon sorting)

* Easy checking of chain breakages
