TALLASOur goal is to define, extract, and analyze features in the increasingly large and complex datasets produced by state- of- the- art simulation. We present frameworks that allow feature-based analysis of large-scale datasets using limited resources and interactive techniques for exploration. LDAV W. Widanagamaachchi, C. Christensen, P.-T.
