Data Files for Mapping the Conformational Free Energy of Aspartic Acid in the Gas Phase and in Aqueous Solution

The data are divided in sub-projects where different systems were simulated with different force fields. CHARMM_: simulations run with the CHARMM36 force field AMBER_: simulations run with the AMBER FF99SB-ILDN force field OPLS_: simulations run with the OPLS-AA force field Conformations_: ab initio (DFT-B3LYP & MP2) calculations on selected conformers _NV.tar.gz: simulations of neutral Asp in vacuo _ZW.tar.gz: simulations of zwitterionic Asp in water _NW.tar.gz: simulations of neutral Asp in water _ZV.tar.gz: simulations of zwitterionic Asp in vacuo The simulations using force fields were run with the NAMD 2.9 molecular dynamics package and the metadynamics PLUMED 1.3 plug-in. Ab initio geometry optimization and single point calculations were run with Gaussian 09. For a full description of the data files please see the accompanying ReadMe file.
