			This directory illustrates the usage of fix-phonon to calculate the dynamical
			matrix as well as phonon dispersion curve for 1 dimensional diatomic chain.

			The files under this directory:

			1) data.pos : LAMMPS input file
			2) disp.dat : phonon dispersion data from phonon.bin.2000000
			3) in.Ana : LAMMPS input file
			4) in.disp : input file to get disp.dat by phana
			5) log.lammps : LAMMPS log file
			6) map.in : LAMMPS input file for fix-phonon
			7) pdisp.eps : phonon dispersion for 1D monoatomic chain, generated by plot.disp
			8) phonon.bin.2000000 : last output binary file by fix-phonon
			9) phonon.log : log file for fix-phonon
			10) plot.disp : script to generate phonon dispersion curve (manually created)
			11) pdisp.gnuplot : script to generate phonon dispersion curve (auto generated)
			12) README : this file


			To run this example, simply:
			-> lmp -in in.Ana -screen none

			Once done, one can use the auxiliary analysing code "phana" to obtain "disp.dat" based on
			data from phonon.bin.2000000:
			-> phana phonon.bin.2000000 < in.disp

			And then use the gnuplot script file "plot.disp" to generate pdisp.eps:
			-> gnuplot plot.disp

			The resultant ``pdisp.eps'' compares the measured phonon dispersion to analytic solutions.


			NOTE: the binary file provided here might be unreadable on some computers because of
			incompatibility between different architectures.
			The running of this example needs the molecule package included in lammps.
