A brief overview of the open-source software packages I maintain are listed below:
sumo: Heavyweight plotting tools for ab initio calculation data.
materials-toolbox: A collection of small python and bash scripts to help with computational chemistry work (especially for those using VASP).
bapt: A script to plot publication-ready electronic band alignment diagrams.
galore: A package to apply Gaussian and Lorentzian broadening to data from ab initio calculations.
