/* ERROR/WARNING messages:

E: Atom_style line can only be used in 2d simulations

Self-explanatory.

E: Per-processor system is too big

The number of owned atoms plus ghost atoms on a single
processor must fit in 32-bit integer.

E: Invalid atom type in Atoms section of data file

Atom types must range from 1 to specified # of types.

E: Invalid density in Atoms section of data file

Density value cannot be <= 0.0.

E: Assigning line parameters to non-line atom

Self-explanatory.

E: Inconsistent line segment in data file

The end points of the line segment are not equal distances from the
center point which is the atom coordinate.
