Further additions to <i>MolScript</i> version 1.4, including reading and contouring of electron-density maps

Abstract

MolScript is one of the most popular programs for the generation of publication-quality figures and the recent re-working of the program should ensure its continued popularity. However, some functionality of particular interest to crystallographers is not part of the standard program. A modified MolScript version 1.4 has been described previously, with more flexible colouring schemes among its new features. This report describes further enhancements to MolScript version 1.4, including facilities for drawing rods for helices and ribbons for oligonucleotides and allowing several formats of electron-density maps to be read and contoured using either lines or smoothed triangulated surfaces.
