[gmx-users] Alchemistry free energy simulations of molecules with different atom numbers

2008-11-19 Thread Zhao Lifeng
Dear all, I encountered a problem in alchemistry free energy calculations: In my simulations a group (A) is to be changed to (B) in a molecule, while the atom numbers n(A) is not equal to n(B). A scheme is to include both A and B in the same topology file and switch on/off the B/A charges and vdw

Dear gmx-users,   I’m a new GMX user. I notice from either the user-manual or the references (Palmer, PRE 49 359, & B. Hess, JCP 116, 209, etc.) that there seem to be at least 3 methods available in Gromacs: Einstein relation, TCAF and periodic perturbation method. But I’m not very
