Syntax: connect {<boolean>}
The RasMol connect command is used to force RasMol to (re)calculate the connectivity of the current molecule. If the original input file contained connectivity information, this is discarded. The command connect false uses an extremely fast heuristic algorithmm that is suitable for determing bonding in large bio-molecules such as proteins and nucleic acids. The command connect true uses a slower more accurate algorithm based upon covalent radii that is more suitable for small molecules containing inorganic elements or strained rings. If no parameters are given, RasMol determines which algorithm to use based on the number of atoms in the file. Greater than 255 atoms causes RasMol to use the faster implementation. This is the method used to determine bonding, if necessary, when a molecule is first read in using the load command.
