[lammps-users] help: datafile contains no improper

I am trying to run a sample which has no improper angles. In my input script, I am using the command atom_style: full, I get an error Expecting integer argument in input script , because there are 0 improper angles. How do I define my atom_style to include only atoms, bonds and dihedrals?

Without seeing your data file or input script it's hard to say
what's wrong. But if you're not using impropers, then you
don't need any lines in your input script or data file that
have anything to do with impropers.
