ORTEP (Oak Ridge Thermal Ellipsoid Plot) is a program for drawing crystal structure illustrations. Ball-and-stick type illustrations of a quality suitable for publication are produced with either spheres or thermal-motion probability ellipsoin probability ellipsoids, derived from anisotropic temperature factor parameters, on the atomic sites. There is also a Linux-specific <a href=http://ruby.chemie.uni-freiburg.de/~martin/ortep/ortep.html>Linux ORTEP page</a>.
