The topology was generated using MOL2FF v0.111, with user-defined charges. These charges were obtained using the protocol P3 from Beckstein et al. (J Comput Aided Mol Des, 2012, 26, 635-645): geometry optimization and CHelpG charges calculation using Gaussian03 ( at the HF/6-31G* level, then a two-stage RESP fitting using AmberTools (

Reference validation values

These are experimental values or high-level quantum mechanics values, which will be used for comparison with computed values (found in individual versions).

Files and history

All deposited versions are available and can be downloaded individually. Higher version numbers are more recent. Files that changed between versions can be identified by differing SHA1 hash checksums.
