What is the difference between the tracked_particle_struct and the particle

What is the difference between the tracked_particle_struct and the particle_struct for DPM UDFs?

  In a UDF I am using: " loop(I, Ilist) { loop(p, I->p) { " to loop over all the injections in my simulation and then the each particle in each injection I would then like to get the position of each particle "p" using the macro TP_POS(tp)[i].
  I appear to be getting a problem when i try to call the TP_POS(p)[i] because "p" is in the format of the "patricle_struct" but the macro is looking for "tp" in the "tracked_particle_struct" format.

  Hello,
  Please use the "tp" definition as it will be able to access the position and other related variables for tracked particles.
