Hi, I just upgraded to the newest CCP4 version 6.3 and noticed that libcheck which coot uses to produce restraints from a SMILES string produces garbled coordinates in ccp4 version 6.3 , but the same SMILES string works just fine with CCP4 version 6.2. I tried to get it to fail on public molecules , but couldnt find an illustrative example. But consistently the old version 6.2.2 succeeds but 6.3 garbles the phenyl rings. Anyone else seeing this. Thanks Hari
