Grid convergence of PyGBe with a spherical molecule near spherical surface
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Reproducibility package containing data, running script, plotting script and final plot of grid-convergence study for a spherical molecule near a charged surface.
The running script invokes the open-source bioelectrostatics solver PyGBe with the given input data, computes the solvation plus surface energy and the error with respect to the analytical solution, and plots the final result of convergence.
This result is part of the following publication:

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.
