Supramolecular Architecture of Severe Acute Respiratory Syndrome Coronavirus Revealed by Electron Cryomicroscopy
ABSTRACT Coronavirus particles are enveloped and pleomorphic and are thus refractory to crystallization and symmetry-assisted reconstruction. A novel methodology of single-particle image analysis was… Expand

Automated cryoEM data acquisition and analysis of 284742 particles of GroEL.
TLDR
We demonstrate the potential of the Leginon system for high-throughput data acquisition by describing an experiment in which we acquired images of more than 280,000 particles of GroEL in a single 25 h session at the microscope. Expand

A toolbox for ab initio 3-D reconstructions in single-particle electron microscopy.
TLDR
We have developed a "toolbox" of ab initio reconstruction techniques that provide several options for calculating 3-D volumes in an easily managed and tightly controlled work-flow that adheres to standard conventions and formats. Expand

Towards automated screening of two-dimensional crystals.
TLDR
We have developed working prototypes for several of these tools and tested and evaluated them in a simple screen of 24 crystallization conditions. Expand

Automation in single-particle electron microscopy connecting the pieces.
TLDR
We provide a generic definition of and discuss some of the most important advances in automated approaches to specimen preparation, grid handling, robotic screening, data acquisition, image processing, and computational infrastructure. Expand
