Error in atom format


I am a beginner in LAMMPS. I have generated a 2-d lattice with random
points. Then they are placed in LAMMPS with the read_data file and with
harmonic potential including nearest neighbor interaction.Then I found
the error about some incorrect atom format. I have checked many times but
failed to resolve the issue. In this email I have attached input script,
read_data file along with the log lammps file. I request you to kindly
check and help me to resolve the problem.

You need an extra blank line after the Atoms line.
See the read_data doc page.
