“Interactive Visualization of Spikes, Pores, and Cages”

Filtering, segmenting, and modeling structures in tomograms is often of necessity done by hand and eye with interactive software.
Where algorithmic methods are feasible, interactive analysis is used to determine input parameters and assess computational results.
Achieving optimal results requires facile interactive data exploration. I’ll demonstrate how software we develop for visualizing tomograms can be used to explore possibilities for subtomogram averaging in specific data sets, showing recent improvements to our UCSF Chimera visualization package in the areas of filtering, slicing, masking, boxing particles, symmetry evaluation, missing-wedge compensation and fly-through animation.
