Hello everyone I've just started using VMD and I have a question regarding how to build a polymer for subsequent molecular dynamics runs. I can build (or obtain) monomer units in pdb format but how can I tell the computer to put them in a specific sequence in a random manner as to create an actual coiled chain? For example I want to build a polyethylene chain and I need two CH3 units (chain ends) and a CH2 unit (monomer). I need a way to put the CH3 units in the end and the CH2 units connected with the torsion rotations in a random manner.
