The program dynmat.x generates the XSF file with all vibrational modes.
These are stored as "forces" in the XSF file, which means that in
xcrysden you can see them via "Display-->Forces" menu. The vibrational
modes will be then displayed one at a time with "arrows".

For the description of the dynmat.x program and its input, see the
beginning of PHonon/PH/dynmat.f90 source file.
