Molcas Grid/Geometry Viewer/Editor (GV) is an OpenGL based code for visualization of molecular orbitals and densities, density differences and sp in-densities, and visualization of molecular structures (with the possibility to manipulate them on the screen), and visualiza-tion of some properties.
GV can operate with different kinds of files: •grid files (usually with extension grid) (generated by the program GRID IT), •XYZ files, •molden files, generated by Molcas. If a file name is specified in a command line, GV will determine the type of the file, and switch to the appropriate mode. If no file is specified, GV will search the current directory for files with a known type. GV can run as a ordinary Molcas module (via command molcas gv filename), or as a stand alone executable.
