Reproducible Spectrum and Hyperspectrum Data Analysis Using NeXL

NeXLis a collection of Julia language packages (libraries) for X-ray microanalysis data processing.NeXLCoreprovides basic atomic and X-ray physics data and models including support for microanalysis-related data types for materials andk-ratios.NeXLMatrixCorrectionprovides algorithms for matrix correction and iteration.NeXLSpectrumprovides utilities and tools for energy-dispersive X-ray spectrum and hyperspectrum analysis including display, manipulation, and fitting.NeXLis integrated with the Julia language infrastructure.NeXLbuilds on theGadflyplotting library and theDataFramestabular data library. When combined with theDrWatsonpackage,NeXLcan provide a highly reproducible environment in which to process microanalysis data. Data availability and reproducible data analysis are two keys to scientific reproducibility. Not only should readers of journal articles have access to the data, they should also be able to reproduce the analysis steps that take the data to final results. This paper will both discuss theNeXLframework and provide examples of how it can used for reproducible data analysis.
