To obtain initial guesses for force field parameters of a minimalist 1-1 homo-oligomer model which folds cooperatively into a helix, we developed a simple helical modeling tool which optimizes helical radius (r), pitch (2πc), and the spacing between Lennard-Jones particles (∆t) placed along a helix, given the number of backbone particles (n B ) and Lennard-Jones σ and ε parameters. The spacing between backbone particles is assumed equal, such that the ∆t parameter fully defines the particle positions for a given radius and pitch. The objective function to minimize is the total energy of the particles placed along the helix, considering only the untruncated Lennard-Jones 12-6 function and no bonded terms nor exclusions. The helix is represented by the following parametric equations:
