The IDES Relativity Electrostatic Subframing System multiplies the frame rate of cameras on JEOL TEMs. Microscopes equipped with Relativity achieve exceptional time resolution, data throughput, and advanced automation capabilities. Addition of Relativity allows current JEOL TEM users to forego expensive camera upgrades to their existing systems, instead relying on installation of an electrostatic optics assembly in a wide-angle camera port. These optics rapidly deflect the image data to different regions (subframes) of the camera in a programmable sequence. Each camera readout contains a tiled array of crisp, blur-free subframes. Raw data is automatically analyzed to give a stack of open format images that are loaded back into the camera control software for viewing or further analysis.

Tomographic and microED data sets created by SerialEM are single files with the data stored typically as 16-bit signed or unsigned integers. When these files have to be copied from the computer onto a USB drive, problems can arise.

Cryo-EM has enjoyed an enormous ground swell in popularity ever since the advent of more stable and automated electron microscopes, suitable movie-type cameras, and improved acquisition software. Results obtained so far have been nothing short of spectacular as illustrated by several structures in EMDB and EMPIAR solved by cryo-EM to resolutions better than 1.5Å, such as EMD-31314, EMD-33707 and EMD-35984, the latter of which reaching true atomic resolution. This note describes the workflow used in Single Particle Analysis (SPA) cryo-EM workflows with the Osaka framework, i.e. a set of scripts that work with SerialEM.

TEM is an ideal technique for analyzing metals to gain an understanding of their structural and elemental properties on the sub-micrometer to atomic scale.
