Hello,
I have several questions about MMPBSA scientific background, maybe trivial,
and especially the for the entropic effect. If I have correctly understood
the method, the solute entropic effect is divided into four parameters :
translation, rotation, vibration and configuration.
In the MMPBSA tutorial I found that the configuration term is "the
configurational entropy contribution from sidechain reorganization. Note that
configurational entropy is neglected in this protocol, but may be
significant." Why only sidechain? If you start with 3 trajectories (ligand,
target and complex) this effect couldn't be overcome?
The translation and rotation terms came directly from statistical mechanics.
Therefore, why these values are only accessible with the normal mode option?
Best regards.
