Grid convergence of PyGBe with immunoglobulin G near a charged surface

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.

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.
