dump command

Dear lammps users,

If I have 1000 atoms in a system & all are identical (same type id), can I dump the position/velocity of 100 atoms in a file,next 100 atoms in another file and so on? I badly need a very long trajectory for calculating correlation length.For that I have written my own code.First I have dumped all particle positions in a single file,for very long run time.So I am getting some error with dimension allocation.So can I dump the particle positions for long run in several file (with respect to particle number)?

thanks in advance.

You can define ten groups and ten dump commands, one for each group.
