[Chimera-users] Converting sdf file into mol2 format

Your coordinates are two-dimensional, not three-dimensional. Chimera is not going to be able to correctly determine the atom types for a two-dimensional compound, nor appropriately protonate it, nor properly minimize it. You could directly write a two-dimensional mol2 file from the sdf simply by dropping the runCommand("minimize") step of the processing script, but many of the mol2 atom types would be wrong.
I think you need to use some other tool for your conversion. Maybe Open Babel?
