Q molecular dynamics package: classical molecular dynamics, linear interaction energy (LIE), linear response approximation (LRA), free energy perturbation (FEP), and empirical valence bond (EVB) simulations.
The initial values for alpha and beta in LIE equation are 0.18 and 0.5, respectively. Several groups use iterative LIE approach, i.e. training LIE model to obtain optimal alpha and beta values by using experimental data (e.g. refer to Article Improved Ligand-Protein Binding Affinity Predictions Using M...
