I just started to use VMD, and I want to use the topotools to get the
topology information of polyethylene chain.But for number of bonds,I get the
correct information,but for angles,dihedrals and impropers, it gives 0. I
don't understand why.Can anyone help me with this?

Angles:0 Dihedrals:0 Impropers:0 Cross-terms:0
Bondtypes:0 Angletypes:0 Dihedraltypes:0 Impropertypes:0

Thank you!
