Sample images from a time course experiment. The upper row corresponds to a 30 minute time point
and the bottom row to a 90 minute time point. The columns (left to right) correspond to brightfield,
YFP and CFP images. Cell-ID finds and identifies cells in the brightfield images with high efficiency,
gives them a unique ID number that it maintains for that cell through the time course, and copies the
cell location over to any number of fluorescence images. Image from Gordon et.al, 2007.
