Hi, You should contact the tool's authors for that issue. I don't have any experience with it. Good luck Dries Hi Rompaey, Thanks for your valuable advice. As per your advice I went through the paper ( https://www.google.be/url?sa=t&source=web&rct=j&url=http://www.ncbi.nlm.nih.gov/pmc/articles/P

Hi everyone, I want to calculate difference in folding free energy due to certain mutations. I want to follow the slow growth method as mentioned in: http://www.bevanlab.biochem.vt.edu/Pages/Personal/justin/gmx-tutorials/free_energy/02_topology.html However I don't know how to prepare dual topology
