There is no limit to the number of tracks LabTrack can handle, as long as the organisms producing the tracks can be distinguished from one another. The frame rate that will be achieved depends on the number of particles, the complexity of the analysis and the power of the computer. An average laptop will usually be able to handle a few hundred organisms at about 10 frames per second, whereas a powerful desktop computer could handle more organisms, in 3D, and at considerably higher frames rates.
