smiles "c:\Documents and Settings\admin\Desktop\mcd.sdf" ');


?>

 

plz reply

I have moved this to the JChem forum as this is releated to strucutre search, not Instant JChem.

It should be answered soon.

This error message means that the smiles of the query structure is
not correct, the numbers (1 and/or 2)  should be present two times to
sign both ends of the ring closure(s).

For example Nc2ccccc2,  Nc1ccccc1 or NC12CC1CC2  were correct smiles.
