[Silicon Graphics Teaching Laboratory] 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.
