			Self-explanatory. Check the input script syntax and compare to the
			documentation for the command. You can use -echo screen as a
			command-line option when running LAMMPS to see the offending line.

			E: Fix freeze requires atom attribute torque

			The atom style defined does not have this attribute.

			E: More than one fix freeze

			Only one of these fixes can be defined, since the granular pair
			potentials access it.
