saving tracking results as text files.
re-loading track coordinates from text files.

Guillaume @ CBB

Guillaume asked me for advise on quantification of signals. We made some "dream analysis and results" scheme. For three dimensional stack, intensity measurement should be done knowing how z-slice thickness is compared to the z-stepping distance. Numerical aperture, object magnification limits the theoretical thickness of the optical section so this should be kept in mind when taking images for the quantification.
