Hi Noel, Thanks for looking into this ... I'm on vacation right now but I'll try to get back to it when I return after the 18th. I looked through the tautomer code briefly, but nothing jumped out at me. The tautomer code requires a bit of study and doesn't yield to a quick look. Craig On Fri,

I'm not going to spend any more time on this now, but as a brief update, tautomer test will pass if the molecules are copied before writing out as "can". I can only assume that this is because of reperception of some property which invalidates some assumption in the tautomer code. This code uses a

I've edited the SMILES writer so that it doesn't add hydrogens to chiral centers (and fixed the resulting problems)...but tautomer test is still failing. - Noel On 30 May 2012 16:29, Craig James wrote: > Hi Tim, > > When I reverted the SMILES canonicalizer (that is, > SMIBaseFormat::WriteMolecul
