Changes

Where the token elements are '''<mol name>''', the name of the molecule, '''<res id>''', the residue identifier which can be a number, name, or range of numbers, <br>'''<atom id>''', the atom or spin system identifier which can be a number, name, or range of numbers. If one of the tokens is left out then all elements will be assumed to match. <br>For example if the string does not contain the '''#''' character then all molecules will match the string. <br>If only the molecule ID component is specified, then all spins of the molecule will match. <br>Regular expression can, in some instances, be used to select spins. For example the string'''@H*''' will select the protons ‘H’, ‘H2’ and ‘H98’.
