re-run command error

Hi,
I am trying to use the rerun command to run my simulation with a higher cut off energy in order to calculate the rdf. However, I am getting an unknown command error. I cannot seem to figure out what I am doing wrong?

rerun dump.atom dump x y z vx vy vz
ERROR: Unknown command: rerun dump.atom dump x y z vx vy vz

do you use a current version of lammps?

btw: you don't need velocities to compute the rdf.

Hi,
I was running earler version of LAMMPS and updated it to current. What I am trying to do is to re-run the dump so as to compute the RDF at cut-off higher than the original value. Not sure what I am doing wrong, but when I run using the command below, I still get the same cut-off as the original run. Any idea on how to resolve this, or perhaps I am missing something. Kindly, please help

how did you tell lammps to build larger neighbor lists?
those are a prerequisite for the rdf compute to go to
larger distances.

There are 2 ways to do this in the rerun script.

a) use a pair style with a longer cutoff
b) use no pair style, but use the communicate ghost command
    to insure atoms are communicated from far enough away
