Hello,

I ran a simulation for 100ns on 2 nodes (16 cores). I tried to generate replicates with different starting trajectories and ran it on one core, so basically I have 64 replicates with different starting trajectories and I am using 8 nodes. I wish to combine all the .xtc files from each of the replicates and analyze it as a whole.xtc file. So I used this command :

trjcat -f *.xtc -settime -o whole.xtc (and thereafter entering 'C' to continue, to combine all 64 xtc files with different starting time/trajectory)

and I got a total of 350ns combining all the trajectories. I tried to get the rdf for 350ns, but the values stay lower than 1. For 100ns that I ran on 2 nodes I got values for rdf that fluctuate around 1. I tried to break-down 350ns trajectory in 100ns and I got values fluctuating around 1, for all set of 100ns (i.e. beginning 100ns, middle 100ns and last 100ns, similar to 100ns ran on 2 nodes). Shouldn't the rdf be constant after 100ns then? Why do my values stay lower than 1 for 350ns? I am not sure if I am combining the files incorrectly. Could anyone provide some insights?

Thanks.
