Suppose I have a protein PDB file and want to compute energy from the coordinates in the file using the following formula.

How can I do that?

Sometimes people suggest using the CONECT field for that purpose. However, some PDB files do not have this field.

Example: 4OSK.pdb (Crystal structure of TAL effector reveals the recognition between asparagine and guanine)

Not at all my field of expertise, but the AMBER package is what we used in our protein bioinfo classroom exercise back in the day. I think, their force field is different, but I believe you can specify your own.
