The bigger problem seems to be that some of the atom type names are the same as the AMBER forcefields, like H and C. What happens when AMBER and GLYCAM forcefields are loaded simultaneously? Does one replace the other?\r\n\r\nThis is formally undefined and should never happen.  The exception being when the atom type is shared between both force fields and all parameters are equivalent (you can see where this is done via the \"parm10\" comment in the GLYCAM_06j.dat file.\r\n\r\nBut *if* there's a mistake, whichever file is loaded last decides the parameter that is used."}}
