Configuring the View in RasMol command

To change the way the View Molecule in RasMol command operates, use the Configure... button from the Add-in Manager after selecting the View in RasMol Add-in.

Clicking on the Configure button displays a dialog box, which operates as follows:

The OK button closes the dialog and saves the new preferences for the current and future uses of the View Molecule in RasMol command.

The Cancel button closes the dialog box and does not change the preferences.

To define the appearance of a structure in RasMol, check the Start RasMol with script file checkbox and select a RasMol script file. You may type in its full path and file name, or use the Browse button to search for the file.  MDL provides four sample script files, which can be used as a basis for developing your own script files.  The sample script files are installed to the same location as the Add-in files. If a script file is specified, the settings in the script file are used to display the selected structure when the Add-in starts the RasMol application.  If no script file is specified, the structure will appear in wireframe mode.
