Thanks for your reply. I have actually gone to the xmgr file and deleted the extra points and used gnuplot to plot the&nbsp;results. However if I wanna plot things directly using "gs" (i.e reading the points from the xmgr file directly), do I have to add the points in the input file. Why does the xmgr file add more points than the ones given in input? In the bands.dat file, I have the same points as input!<BR>

<DIV>do you know the meaning of each of the "points" that are displayed in the plot? have you counted them? does the count match the number of input points in your band-structure calculations?</DIV>
