Before revision:  The estimated twist-bend coupling coefficient from oxDNA simulations is G=30 (1) nm, in agreement with the value obtained from a recent analysis of magnetic tweezers data (G=40(10) nm) \pm1 \approx 80~nm, which is different from the intrinsic torsional stiffness C \approx 110~nm.
After revision:  The estimated twist-bend coupling coefficient from oxDNA simulations is G=30 (1) nm, in agreement with the value obtained from a recent analysis of magnetic tweezers data (G=40(10) nm) \pm1~nm. The groove asymmetry induces a novel twist length scale and an associated renormalized twist stiffness \kappa_{\rm t \approx 80~nm, which is different from the intrinsic torsional stiffness C \approx 110~nm.
