A couple problems with this one:
- The first SMARTS pattern in the sample file -- [N0;H0;D1;v3] -- is, I'm pretty sure, illegal SMARTS. It should be [N+0;H0;D1;v3]
- The example moleculem, caffeine, contains one of those wonderful ring systems where one can argue about aromaticity. For toolkits that consider the six-ring to be aromatic (e.g. the RDKit), the TPSA is 61.82

The value example value of the PSA originally provided was incorrect according to Peter Ertl's online calculator.
