Thanks Ken! It was really helpful :) I've used Chemistry::MolecularMass module to have precise atomic weights.

    I haven't used Chemistry::MolecularMass previously (in fact, I wasn't aware of its existence until now); however, looking at its documentation, it would appear another (completely untested) solution would be:

    use Chemistry::MolecularMass; my $mm = Chemistry::MolecularMass::->new(); $mm->replace_elements(H => 0); my $no_H_mass = $mm->calc_mass($your_formula);
