It has shown up. Several times. Search the archives for previous answers.

and .trr files. I want to color my particles based on rmsd, potential energy,
Sg (tetrahedral parameter) or any other parameters in a specific configuration.
Is there a way to extract individual particle’s properties out of these

Some GROMACS tools can write PDB files that have the B-factor field filled with a relevant datum (e.g. atomic RMSF) but probably you"ll need to apply g_energy or other tools and your own scripting. Potential energy is a particularly useless thing to colour by.
