A list of ~19 million perovskite composition strings, delimited by newlines. These are the perovskites screened in "Machine Learning Materials Properties with Accurate Predictions, Uncertainty Estimates, Domain Guidance, and Persistent Online Accessibility" by Jacobs et al. (link) Derived from files shared on FigShare. This text file is essentially just the first column of all the subfiles in MATERIALS_SCREENING_NEW.zip. This file is helpful for reproducing the screening from scratch.
