Mtrack2, mutitracker and all ofthe tracker plugins fails to show me the paths

I was working on mtrack2 and i don’t know what happened, but now I’m unable to create any paths.
I set the properties by default and nothing. Even the example for Multitracker functions. I do not know what to do. please Help!

I reinstalled fiji, download the plugins…

what can I do?

Hi and welcome :slight_smile:
It is difficult to know how to help without knowing what changed between when it worked, and when it stopped working.
Do you have screenshots of your attempts? Any errors?
