Dear Rajesh, For your first question, I think if you plot the wavefunction from SystemLabel.bands.WFSX, then the answer is yes. The program Denchar plot the wavefunctions of selected bands (controlled by options: WFS.Write.For.Bands, WFS.Band.Min, WFS.Band.Max) for all the k points that you specify in %block BandLines. In the SystemLabel.bands file there is same number of k points.
Of course you can reduce the number of k points by using %block WaveFuncKPoints. Then you use denchar and plot the data from SystemLabel.selected.WFSX (cp SystemLabel.selected.WFSX SystemLabel.WFSX). I don't think this option will affect the charge density in SystemLabel.RHO file.

Is it the number given in %block BandLines? What if I calculate for some selected bandlines to reduce this k-point number using SystemLable.selected.WFSX, will it give me the complete charge density? Your help and suggestions would be highly appreciated. -Rajesh
