Description: ISODISTORT is a tool for exploring the structural distortion modes of crystalline materials. It provides a user-friendly interface to many of the algorithms used by the Isotropy Software Suite, allowing one to generate and explore distortion modes induced by irreducible representations of the parent space-group symmetry. It also provides a Java applet for visualizing and interactively manipulating the free parameters associated with these modes.

Java Alert: We have learned a bug was introduced into new subversions of Java 6.x and 7.x that effects the interactive ISODISTORT and ISODIFFRACT applets, so that many of the controls are not fully visible. The problem will allegedly be fixed in some future version of Java. As a temporary work-around, try adding "-Dsun.java2d.d3d=false" (without the quotes) as run-time parameter in your Java console. See this link for more information. Please let us know if this doesn't solve the problem.
