To determine which model would be used as the initial coarse-grained model, average characterizations of multiple versions were analyzed. Each version was simulated for 10 ns during the production run with the v-rescale thermostat and the Parrinello-Rahman barostat at 310 K and 1 bar. Table shows the average characterizations for the ST, RHT, and LHT conformations for the LJ σ=0.34 and ϵ=0.75 version. It appears that the h in the ST conformation is close to the experimental value of 0.34 nm. The experimental value is the minimum distance between the rosette rings due to steric hinderances, so the coarse-grained model's h can be larger than the minimum distance of 0.34 nm. On the other hand, the RHT and LHT conformations have h's that are much larger, sicne the nanotube length is more than double that of the ST conformation. It appears that the helical nanotubes coarsegrained models need to be further optimized to stay closer to their experimental lengths.
