We present the results of high temperature 500 K Molecular Dynamics simulations of a single-stranded DNA i-motif. The unfolding pathways are compared to a biased metadynamics simulation at 300 K. Our results indicate a remarkable agreement between the trajectories. We found that the unfolding process can be described by two main mechanisms with a small number of eigenvectors.
