Paratec can produce Data Explorer and Khoroshttp://www.khoros.unm.edu/ files that visualize wavefunctions at particular kpoints, bands. The square of the wavefunctions is plotted in realspace. Wave function plotting is switched on by setting pw_job scf and output_flags waveplot.
The wave functions to be plotted are specified as pairs of the irreducible kpoint number and band number.
Example:
begin plot_wave_function wavefunction 1 12 irreducible kpoint 1, band 12 wavefunction 2 10 irreducible kpoint 2, band 10 end plot_wave_function
