Eadfrith

If you want to look at a molecule quickly, without starting MacroModel or Cosmic, type eadfrith Filename. You will get the following messages:

 Use ESC key to exit, SPACE to render
 LEFTMOUSE to enlarge,
 MIDDLEMOUSE to rotate, RIGHTMOUSE to move.
 Options:
 (A) Radii: 1.000000 
 (B) Bond Option: 0
 (C) Picture in window
 (D) Full contrast
 (E) Background colour (RGB): 0 0 0
 (F) New Orientation
 (G) No NMA
 (H) Standard Colours
 (I) No Initial Depth Cue
 (J) Line Width: 1
 (K) Ambient Light 0.5000000 
 (L) Bond radius  0.3000000
 (*) Quit
 Enter a letter, then RETURN, to alter options
 or press RETURN to continue

Press RETURN immediately to display your molecule. It will appear in a new window, and can be rotated, enlarged and moved using the mouse. A rendered version can be made by pressing the space bar. The window can be killed by pressing the ESC key (top left of the keyboard).

To alter the settings, type a letter, then press return. You may then be asked for more information. The options control the picture in the following ways:

  • A: Alter the radius of the rendered spheres (drawn when the space bar is pressed). 1.0 gives a ball and stick model; 4.0 gives a CPK model.
  • B: Controls the colouring of the rendered bonds.
  • C: Toggles between a new window and filling the screen with the molecule.
  • D: Controls the contrast in the rendered picture.
  • E: Controls the colour of the background. 0, 0, 0 gives a black background; 255, 255, 255 give a white background. The first number is the red component of the colour, the second is the green component, the final number is the blue component.
  • F: Decides whether to use the orientation of the previous molecule, or to use a new orientation.
  • G: This option enables you to animate normal mode analyses.
  • H: This switches between using standard colours, or reading them from the file.
  • I: Turns depth cueing on or off while molecules are rotated.
  • J: Determines the width (in pixels) of the lines that make up the molecule.
  • K: This figure is the ratio of ambient to directional light in the rendered figure.
