ERROR:Unknown identifier in data file

Dear lammps-users:
My data file has the error of unknown identifier,but i don’t know why it happens. I search the Internet, and someone says that if the data mess up, it will has this error, but i think my file has a good order. Please help me find out what’s wrong with my data file, is it because it’s too large?


data.cutting.tar.gz (9.09 MB)

The # of atom lines in the file does not match what the header
of the file says:
2059887 atoms

Do a wc on the file and you'll see the difference.
