MARTINI model of the ST RNT by introducing partial charges to the TP1 and TP2 beads as well as adding phantom VK beads in the center of the nanotube. This added stability to the nanotube structure during the course of the simulation, as shown by the nanotube length and axial rise in Table . However, this initial model did not reproduce the nanotube length or the axial rise for the LHT and RHT conformations of the RNT.
