RasMol Scripts

MarvinView can execute scripts containing 3D viewing commands delimited by semicolons or newlines. Comment lines start with #. Currently, only the following subset of RasMol/Chime commands is implemented:

ballstick
ballstick on
ballstick true Ball & stick rendering style.
This command is Marvin-specific.

center
center atomno
center [x, y,z]

centre
centre atomno
centre [x, y,z]
Defines the center point for the rotate and zoom commands. Without argument, the center is set to be the center of gravity. The argument can be an atom number, or three coordinates specifying the distance from the center of gravity. The x, y, z values are in RasMol units (1/250 Angstrom).

cpk Synonymous with spacefill.

delay
delay seconds Delays the continuation of script execution for the specified number of seconds. Default delay value is 1 second.

echo text Prints a message to the standard output.

exit Exits from the script. In case of nested scripts, it terminates only the current level.

load molfile Loads a molecule file from the specified URL.

quit Exits from the script interpreter. Terminates all nested levels of scripts.

refresh Redraws the current image. In Marvin, this command is not necessary because the image is automatically refreshed at the beginning of delay commands and at the end of script.

reset Restores the default viewing transformation.

rotate x angle
rotate y angle
rotate z angle Rotates about the "x", "y" or "z" axis with the specified angle (degrees).

script file
source file Reads a script from the specified URL.
Scripts can be nested without any depth limitation in Marvin.

spacefill
spacefill on
spacefill true Atoms are represented by balls, bonds are not drawn.

sticks
sticks on
sticks true Sticks rendering style.
This command is Marvin-specific.

wireframe
wireframe on
wireframe true Bonds are represented by lines in wireframe mode.

wireknobs
wireknobs on
wireknobs true Wireframe with knobs.
This command is Marvin-specific.

zap Deletes molecule and resets parameter variables to their default values.

zoom percentage Magnifies to the specified value.

Warning: RasMol support is incomplete and experimental.

`ballstick` `ballstick on` `ballstick true`	Ball & stick rendering style. This command is Marvin-specific.
`center` `center` atomno `center [`x`,` y`,`z`]` `centre` `centre` atomno `centre [`x`,` y`,`z`]`	Defines the center point for the `rotate` and `zoom` commands. Without argument, the center is set to be the center of gravity. The argument can be an atom number, or three coordinates specifying the distance from the center of gravity. The x, y, z values are in RasMol units (1/250 Angstrom).
`cpk`	Synonymous with `spacefill`.
`delay` `delay` seconds	Delays the continuation of script execution for the specified number of seconds. Default delay value is 1 second.
`echo` text	Prints a message to the standard output.
`exit`	Exits from the script. In case of nested scripts, it terminates only the current level.
`load` molfile	Loads a molecule file from the specified URL.
`quit`	Exits from the script interpreter. Terminates all nested levels of scripts.
`refresh`	Redraws the current image. In Marvin, this command is not necessary because the image is automatically refreshed at the beginning of `delay` commands and at the end of script.
`reset`	Restores the default viewing transformation.
`rotate x` angle `rotate y` angle `rotate z` angle	Rotates about the "x", "y" or "z" axis with the specified angle (degrees).
`script` file `source` file	Reads a script from the specified URL. Scripts can be nested without any depth limitation in Marvin.
`spacefill` `spacefill on` `spacefill true`	Atoms are represented by balls, bonds are not drawn.
`sticks` `sticks on` `sticks true`	Sticks rendering style. This command is Marvin-specific.
`wireframe` `wireframe on` `wireframe true`	Bonds are represented by lines in wireframe mode.
`wireknobs` `wireknobs on` `wireknobs true`	Wireframe with knobs. This command is Marvin-specific.
`zap`	Deletes molecule and resets parameter variables to their default values.
`zoom` percentage	Magnifies to the specified value.
