ERROR on proc 0: Unknown identifier in data file

Hi everyone!
Can anybody help me in understanding what is wrong in this data file? The error message I got when trying to run the simulation is "ERROR on proc 0: Unknown identifier in data file: 33 8 4 0.417 -4.422 -0.777 2.127 (read_data.cpp:1396)". I have given a look to the error section in the manual, but I didn't get what the exact error was.
I am very confused!
Thanks a lot,
Davide

the doc page says: “A section of the data file cannot be read by LAMMPS.”
maybe you should check if the formatting of your data file is sain… (or appropriate for the atom style you use)

One possible source of error is that you did not have the correct
number of atoms and atom types; e.g., only 32 atoms or 7 atom types.

I think that's correct. I would guess that the number of lines in the
"Atoms" section of your data file exceeds the number at the top of
your data file. In other words, if at the top of this file, it says
"10347 atoms", then your Atoms section should contain 10347 lines (but
yours has more). I could be wrong, but check that.
