The trajectory of SSD states visited during a conventional MD simulation of the G4-K-G4 peptide over a crystalline PLA surface. The trajectory shows that the peptide is held tightly to the surface, thus providing a serious sampling problem that prevents the use of Eqn. 1 for the calculation of adsorption free energy.
