Therefore, i do not see the positive bands<br><br>However, in the file case.spaghettti_ps all the band structures (positive and negative) are plotted<br><br>After searching in the files generated by "x spaghetti -p", i detect that the -1.28 ev seen in case.bands.agr corresponds to the upper band number 999,<br><br>My goal is to see all the bands in case.bands.agr using xmgrace<br><br> However, when i change the parameter 999 in case.insp and i set it to 2000 (for example), the same behavior<br>will also be seen in case.bands.agr<br><br>My question is how to go upper than the band number 999 to see all bands (positive and negative in case.bands.agr) ?<br><br>Waiting for your help, i would to thank you all<br><br>Sincerely yours<br><br>Ali ALLAM<br>PhD in physics of materials<br>Aix-Marseille University<br>Av Escadrille Normandie-Niemen<br>Marseille 13013, France<br><br></div> </div></div> </div></body>
