The parameter

<Angle smirks="[H:1][C:2]([H])([H])[CH:3]=O" angle="109.5 * radian" k="50.0 * mole**-1 * radian**-2 * kilocalorie" id="A14SB-MainChain_PRO-HC_CT_C"></Angle>

However, if I change it to [H:1][C:2]([H])([H])[C:3]=O, it works fine. I need to figure out how to systematically apply this change in the conversion script.
