Dear Chimera users,

I want to perform molecular docking by using Swiss Dock. Therefore, I have used Chimera to remove the molecules that I don’t want from the PDB file, add hydrogens and save as mol2. However, when I tried to upload the mol2 file in SwissDock I get this error:  “Ligand setup failed. Please check that your structure file has a correct topology. No extra info available”.

Does anyone know what I am doing wrong?

Thank you in advance,

C.
