Syntax: set hydrogen <boolean>
The RasMol hydrogen parameter is used to modify the `default' behaviour of the RasMol select command, i.e. the behaviour of select without any parameters. When this value is false, the default select region does not include any hydrogen or deuterium atoms (refer to the predefined set hydrogen ). When this value is true, the default select region may contain hydrogen atoms. This parameter is similar to the RasMol hetero parameter which determines whether heterogenous atoms should be included in the default set. If both hydrogen and hetero are true, select without any parameters is equivalent to select all.
