Good morning I would like to appreciate your work and efforts in developing and maintaining ChimeraX, it has always been so useful tool in my research. I was initially using Chimera that had excellent feature of using amber force field for energy minimization of structure and making movie using topology and coordinate file. I am working on inducing mutation in nucleic acid and protein structures. I wish to incorporate the minimization step in my research using Chimerax. I will be highly grateful if you could guide me how can I use minimization steps in Chimerax using command line codes. Thank you Tushar Gupta PhD biotechnology Bennett University Greater Noida India "He that can have patience can have what he will." - Benjamin Franklin _____________________________________________ Vineet Jain (Chancellor) Inspiration
