 This tutorial shows step-by-step, how the "Lifetime FRET Image" analysis of SymPhoTime 64 can be used to calculate pixel-by-pixel the average [[glossary:fret|FRET]] efficiency in an image containing several cells transfected with Cerulean/YFP-constructs. To calculate the average FRET-efficiency, first the donor only lifetime is determined using cells that have only been transfected with the donor construct by performing a ROI-fit with the FLIM-analysis. The amplitude weighted average donor lifetime is used to calculate the average FRET-efficiency using the "Lifetime FRET Image" analysis.

+===== Background information =====
 FLIM-FRET is a robust method to determine the FRET efficiency of a suited donor acceptor pair.
 If the FRET-donor molecule has a more exponential decay kinetic, the amplitude weighted average lifetime has to be used to calculate the average FRET efficiency.

     * To analyze many images with the same FRET pair, it is possible to save the starting values for the fits by clicking on "Save Defaults" and store the starting values as a User Profile by entering the main menu ("Settings\Save User Profile as"). The software will need to restart to adapt the changes.
