Thanks very much for thre clarification. It did really help and I got all results and graphs as expected.

You will find attached the input file and the ps file. Regards Elie What you look on the plot exactly corresponds to what you wrote in your input: - the first two "places with no point" correspond to the points: 0.39 0.39 0.00 0.10 0.40 0.30 0.00 0.10 0.41 0.41 0.00 0.10 it is evident the "misprint" (0.30 instead if 0.40) - the third "place with no point" corresponds to: 0.50 0.50 0.00 0.10 0.50 0.00 0.00 0.10where you "jump" from 1/2 1/2 0 to 1/2 0 0 What bands.x does is to convert YOUR k-point list in such a way that x[i+1] = x[i] + | k[i+1] - k[i] | where x is the abscissa on the band structure plot whereas k[i] is the i-th k-point vector, and |...| indicates the modulus. So if there are "unwanted" jumps in your list, this will result in points that look "unexpectedly" far from each other. So, there are not "places with no points". The code is at the moment quite robust in doing exactly what the user asks, I guess that there are ongoing developers' efforts in designing it to do what the user wants!!!!!!!! ;-) Hope this helps, Giovanni -- Dr. Giovanni Cantele Coherentia CNR-INFM and Dipartimento di Scienze Fisiche Universita' di Napoli "Federico II" Complesso Universitario di Monte S.
