The user does not need to input bond lengths and bond angles. The program should be able to estimate them. It should look like a molecular builder in the sence that it can put together the fragments with fixed bond lengths and bond angles, but take torsion angles as variables. I would imagine that there exists this kind of routine for some specific categories of molecule such as proteins and DNA. My question is wether there exists such routine for a general organic molecule? What about availability? Thank you in advance! Jing Kong Dalhousie
