Replica exchange molecular dynamics simulation analysis?

GROMACS version: 2020.4
GROMACS modification: No
I have simulated a protein complex using REMD simulations with 9 replicas for each system. Now, I am not able to find a tutorial or hands on guide for analyzing the data. If anyone can guide me no the analysis part, how to use the different replicas obtained and also what all different analysis can be done apart from the regular RMSD, RMSF, Rg etc. What commands to be used and with which trajectories?
