• ISODISTORT is a web-based tool for exploring structural distortions in solids. The program takes CIF files combined with user input and reports group-subgroup relationships based on normal-mode analysis, visualizing them using the ISOVIS program. These reports could include CLEG-based summaries of the path from a parent to child structures, and the Java+JavaScript ISOVIS program could be augmented by embedding Jmol within it.
