Grass: A server for the graphical representation and analysis of structures

GRASS (Graphical Representation and Analysis of Structures Server), a new web‐based server, is described. GRASS exploits many of the features of the GRASP program and is designed to provide interactive molecular graphics and quantitative analysis tools with a simple interface over the World‐Wide Web. Using GRASS, it is now possible to view many surface features of biological macromolecules on either standard workstations used in macromolecular analysis or personal computers. The result is a World‐Wide Web‐based, platform‐independent, easily used tool for macromolecular visualization and structure analysis.
