Dear KNIMErs,
I found a problem while I was using the Openbabel node to convert a molecule to mol2 format. As you can see in the attached workflow (using the “Mol2 string render”), when I use the Openbabel KNIME node (using the bundled version of openbabel) it results in a mol2 format structure where atom types are not correct. They miss points (e.g. “Car” instead of “C.ar, Npl instead of N.pl, etc.). This results in invalid structure that cannot be well displayed by the molecule renders.
I also checked that the problem is not due to openbabel itself because if I run the transformation by an external version of Openbabel (through the External Tool Lab node) the resulting format is correct.
So in my opinion this could represent a bug. Can you please confirm that?
Thanks,
Gio
P.S.: I'm using the last current version of "KNIME Base Chemistry Types & Nodes" (3.2.2.v201609201941)
