Grid convergence of PyGBe with immunoglobulin G near a charged surface

dataset
posted on 25.03.2015 by Christopher D. Cooper, Lorena A. Barba

Reproducibility package containing data, running script, plotting script and final plot of grid-convergence study for immunoglobulin G near a charged surface.

The running script invokes the open-source bioelectrostatics solver PyGBe with the given input data, computes the extrapolated value of solvation plus surface energy (with Richardson extrapolation), and plots the final result of convergence.

This result is part of the publication:

"Probing protein orientation near charged nanosurfaces for simulation-assisted biosensor design," Christopher D. Cooper, Natalia C. Clementi, Lorena A. Barba; J. Chem. Phys., Vol. 143: 124709 (2015)

PyGBe solves biomolecular electrostatics problems using an implicit-solvent model (Poisson-Boltzmann) and it uses GPU hardware for fast execution. It is written in Python, PyCUDA and CUDA.
