Sir, I also have come across several papers where they have done single simulations but in recent days most of them perform multiple trajectories for shorter period. But I am not clear how can multiple trajectories for shorter period of time compensate for single extended time simulation. Thank

Sir, Thank you for the reply. Total simulated time is 50ns. first 4ns is left and only 4-50ns were considered for rmsf calculations. T1 is 300K and T2 is 363K the protein being simulated is from Ecoli (mesophilic). As you have mentioned I do not have replicates of simulations hence only one 50ns

Sir, Thank you for your suggestions. I decided the cutoff based on RMSD convergence. I will calculate at different time intervals. Running multiple simulation is definitely the best suggestion but due to time and machine constraint it would be difficult. Instead I have two mesophilic simulations.
