NAME

molecule - draws 3D molecular structures

SYNOPSIS

molecule [-display host:display.screen] [-window] [-root] [-visual visual] [-delay microseconds] [-wander] [-no-wander] [-spin axes] [-no-spin] [-timeout seconds] [-labels] [-no-labels] [-titles] [-no-titles] [-atoms] [-no-atoms] [-bonds] [-no-bonds] [-shells] [-no-shells] [-molecule file-or-directory] [-verbose] [-wireframe] [-fps]

DESCRIPTION

The molecule program draws several different representations of molecules. Some common molecules are built in, and it can read PDB (Protein Data Base) files as input.

OPTIONS

molecule accepts the following options: -window Draw on a newly-created window. This is the default. -root Draw on the root window. -install Install a private colormap for the window. -visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. -fps Display the current frame rate, CPU load, and polygon count. -verbose Print debugging info on stderr about files being loaded, etc. -wander Move the molecules around the screen. -no-wander Keep the molecule centered on the screen. This is the default. -spin Which axes around which the molecule should spin. The default is "XYZ", meaning rotate it freely in space. "-spin Z" would rotate the molecule in the plane of the screen while not rotating it into or out of the screen; etc. -no-spin Don't spin it at all: the same as -spin "". -labels Draw labels on the atoms (or the spot where the atoms would be.) This is the default. -no-labels Do not draw labels on the atoms. -titles Print the name of the molecule and its chemical formula at the top of the screen. -no-titles Do not print the molecule name. -atoms Represent the atoms as shaded spheres of appropriate sizes. This is the default. -no-atoms Do not draw spheres for the atoms: only draw bond lines. -bonds Represent the atomic bonds as solid tubes of appropriate thicknesses. This is the default. -no-bonds Do not draw the bonds: instead, make the spheres for the atoms be larger, for a "space-filling" representation of the molecule. -shells Draw transparent electron shells around the atoms. This only works if bonds are also being drawn. -no-shells Do not draw electron shells. This is the default. -shell-alpha When drawing shells, how transparent to make them. Default 0.4. -wireframe Draw a wireframe rendition of the molecule: this will consist only of single-pixel lines for the bonds, and text labels where the atoms go. This will be very fast. -timeout seconds When using the built-in data set, change to a new molecule every this-many sec‐ onds. Default is 20 seconds. -molecule file-or-directory Instead of using the built-in molecules, read one from the given file. This file must be in PDB (Protein Data Base) format. (Note that it's not uncommon for PDB files to contain only the atoms, with no (or little) information about the atomic bonds.) This can also be a directory, in which case, all of the .pdb files in that direc‐ tory will be loaded. A new one will be displayed at random every few seconds (as per the -timeout option.) When the molecule is too large (bigger than about 30 angstroms from side to side), the -label option will be automatically turned off, because otherwise, the labels would over‐ lap and completely obscure the display. When the molecule is around 150 angstroms from side to side, wireframe mode will be turned on (because otherwise it would be too slow.)

ENVIRONMENT

DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
