Insert structures in Databases and Tautomers

Hi:


When I insert an structure in the database with the option in the JChem


Table that check duplicates with tautomers, the program insert the


tautomrized structure of the compound or the original structure?





And the second question?


With this option the performance of the insert operation is very slow, how


can I fixed this problem?


Thank in advance...

No, the original structure is inserted.


The only difference is in the calculation of the hash code (cd_hash), used for duplicate filtering.





Regarding speed I wrote some remarks in this topic:
