How to make particles stay on the ground (trail effect)

Hi there.
I am a newbie and as such I would need your help.

I am trying to apply a particle effect using Trapcode Particular to a mountain bike wheel.
The problem is that the footage has a camera pan to the right and I don't know how to apply the tracking I got from mocha. I want the particles to "stay on the ground" but I can't understand what to do.
This is a link to the footage I am working on:

Hope you guys can help me out.

Hi there,

It's not a straightforward job but what you'll have to do is use expressions to link the tracking data from Mocha to the Particular properties. If you've never used expressions before I recommend these websites to help you get started;

Hope this helps!
