[Chimera-users] Problem with minimizing structure

Hello all, I am having a problem with the minimizing structure function in Chimera. I am just trying to change a single residue on a very small protein (88 residues), but I keep getting the error: No MMTK name for atom "H1" in standard residue "GLN". Previous message boards seem to just point to bug fixes in Chimera, but I am running the newest version available for Windows 10. I would appreciate any help! Thanks so much, Renee
