How do I run COMBOSA scripts in RasMol?
On Windows platforms copy the script and paste it into a text editor. Save the script as a text file (so that it has the .txt extension), and place it in the same folder as RasMol. Load the molecule you wish to examine into RasMol, then type script followed by the name of your text file (include the .txt extension) into the RasMol Command Line window and press enter. For more information on using RasMol see the RasMol manual.
