In the bench directory of lammps there is a chute.data file which is a data file for in.chute. as a data file for a granular system 7 parameters in atoms section should be specified which are atom-id, atom type, diameter, density, x , y , z coordinate. i do not know what are those extra columns in chute.data file for?

you have to read the documentation more carefully.
those are the "image flags".
from the read_data documentation:
each line can optionally have 3 flags (nx,ny,nz)
appended to it, which indicate which image of a periodic simulation
box the atom is in. These may be important to include for some kinds
of analysis.
