about write_data option

Hi there,

I’m trying to simulate polymer in lammps (version 18 Jun 2016-ICMS). To start with the simulation I’m using “read_data” command, and the data file contains all the topology information, e.g. bond/angle/dihedral etc. I want to get lammps data file after each ‘thermo step’, for which I used write_data XXX.* but it is only generating the last step lammps data with full topology information. Is there any way to get data file in lammps data format with full topology information after each desired thermo steps ?

used commands are as follows,
