SURFNET - A PROGRAM FOR VISUALIZING MOLECULAR-SURFACES, CAVITIES, ANDINTERMOLECULAR INTERACTIONS

The SURFNET program generates molecular surfaces and gaps between surf aces from 3D coordinates supplied in a PDB-format file. The gap region s can correspond to the voids between two or more molecules, or to the internal cavities and surface grooves within a single molecule. The p rogram is particularly useful in clearly delineating the regions of th e active site of a protein. It can also generate 3D contour surfaces o f the density distributions of any set of 3D data points. All output s urfaces cart be viewed interactively, along with the molecules or data points in question, using some of the best-known molecular modeling p ackages. In addition, PostScript output is available, and the generate d surfaces can be rendered using various other graphics packages.
