Fluorescence Lifetime Imaging (FLI) is a technique recording the temporal decay of fluorescence emission at every pixel of an image. Analyzing the information embedded in FLI dataset requires either fitting the decay to a predefined model using nonlinear least-square fit or maximum likelihood estimation, or projecting the decay on an orthogonal basis of periodic functions as in phasor analysis. AlliGator is an open source software implementing these approaches in a user-friendly graphical user interface (GUI) offering numerous unique features not found in other existing packages. It leverages the unique ability to design user-friendly GUI of the LabVIEW graphical programming language (G), and supports user-developed plugins written in python.
