New paper in JCIM:
GPU-accelerated ab initio ESP calculations in QUICK + a reweighted RESP (rwRESP) scheme for robust, grid density–independent charge fitting.
Dense molecular grids eliminate orientation dependence in ESP charge derivation. rwRESP removes grid sensitivity and is now integrated into AmberTools.
Open-source and reproducible.
