Figure : Peptides used in our equilibrium simulations to study the conformational preferences two most stable conformations (a R and b ) showed no significant changes in the last 5 ns of the simulation. The collective variables studied were the backbone dihedral angles (F and Y). The bias factor chosen was 6, gaussians were deposited every 500 steps (1 ps) and their width was 0.35 rad in each CV and started at a height of 1.2 kJ/mol. Matplotlib 3.1.1 and the metadynminer package of R a were used for plotting the results.
