we use RoseTTAFold All-Atom to predict the RNA and protein complex(pdb). Try discovery studio, PDB2PQR...,which can be used to do protein prepare. However, we always fail if we set up the CHARMM as our forcefield. This is important to our next experiment and couldn't be changed to other parameter of forcefield. Is there anyone face this problem before or maybe some recommendation to us. thanks for your advice!
