"So you've collected these massive image data. Now what?" Technological advances in cell biological imaging have resulted in the generation of massive amounts of data, yet the ability to handle (store, move, access, use, share) these data often lags far behind, especially in smaller labs and core facilities. Appropriate integration and correlation of disparate data streams at various scales, automated feature extraction, and portability of automated solutions remain daunting. This symposium aims to address issues and solutions stemming from large image data in cell biology, including image processing, correlation and segmentation, as well as archiving, annotating and distributing large data especially in the context of available or open-source options.

Transmission electron microscopy (TEM) and scanning TEM (STEM) reveal the structure of materials across the nano-scale with achievable resolutions below one Ângstrom. However, these are only two-dimensional (2D) projections of complex three-dimensional (3D) structures. 3D morphology and composition are critical to determine the function of nano-structures used across many fields—such as energy, catalysis, and electronics. The success of electron tomography has fueled rapid innovation in quantitative, sub-nanoscale 3D analysis in electron microscopy that include recent achievements of atomic resolution and methods to determine the 3D structure from few or even a single projection image.
