Demo datasets for: ArtiaX: An Electron Tomography Toolbox for the Interactive Handling of Sub-Tomograms in UCSF ChimeraX

ArtiaX is an open-source extension of the molecular visualisation program ChimeraX and is primarily intended for visualization and processing of cryo-electron tomography data. It allows easy import and export of particle lists in various formats and performant interaction with the data on screen and in virtual reality.

This dataset contains cryo-electron tomograms, particle lists, demo command scripts and scripts for performance measurements used for the creation of figures and measurements in the paper "ArtiaX: An Electron Tomography Toolbox for the Interactive Handling of Sub-Tomograms in UCSF ChimeraX"
