Here are the results of another 1.2 million SMILES "shuffle" tests. Each shuffle is 20 randomized versions of one SMILES (so 24 million canonicalizations total).
Most, maybe all of these are repeates of problems we've already encountered, but I thought I'd include them for completeness. I think this brings the total number of molecules I've tested to around 3 million, well over half of our database. It's hard to believe anybody really cares about some of these, but that's what we're here for!
