Response to Comment [arXiv:1407.6854] on Palmer et al., Nature, 510,   385, 2014
  We respond to a Comment [arXiv:1407.6854 (2014)] on our recent Nature paper [Nature, 510, 385 (2014)]. We categorically disprove the arguments provided in arXiv:1407.6854 (2014) and thereby further substantiate the evidence we presented in our recent study, demonstrating the existence of a metastable liquid-liquid transition in a molecular model of water. We will make our code publicly available shortly along with proper user documentation that is currently under development.
