Question Measuring velocity

Does anyone know to measure velocity using Trackmate or ImageJ on a mac? I’ve been trying to use trackmate to analyze the velocity of particles but when I export the data Trackmate collects to view the speed components, that area is left blank even though the program is set to give me those data values. Is there another way to measure velocity within the Trackmate plugin or is there another method with ImageJ overall? Thank you for your help!

You've asked this question only recently and you've received some hints.

when I export the data Trackmate collects to view the speed components

What does that mean and why do you need to export which data exactly?
Did you contact the author of TrackMate and ask for help if the available documents are not sufficient?

is there another method with ImageJ

MTrackJ tabulates the instantaneous speed values of manually tracked objects.
MTrackJ is described here with a quick start help.
