This module provides easy-to-use tools for both on-line and post-capture analysis and exploration of ratiometric data. This includes support for fura-2, indo-1 and BCECF imaging, fluorescence resonance energy transfer (FRET) experiments, and densitometry measurements. The module adds real-time graphing of ratios and intensities, background subtraction, and tracking of multiple objects. It also incorporates post-capture ratio generation, a ratio calibration guide and both direct sensitized FRET and acceptor photobleaching FRET capture protocols and transfer computations.
