Hi Stefano, the problem with the PDBQT format is that connectivity is implicit and bond order is lost. If your atom coordinates are close to ideal (i.e., bond lengths are optimal, non-distorted) you have a good chance of OB to be able to re-build the correct bond order. Although, there's been some discussion in the mailing list about similar problems using PDB files as well. My advice is to manually correct the issues, hoping you don't have too many files to process.

Any suggestion about generating a correct sdf file? Thanks a lot -- Stefano GUGLIELMO PhD Assistant Professor of Medicinal Chemistry Department of Drug Science and Technology Via P.
