<div>Dear users,</div> <div> I have some problems when I calculate the energy band. The space group is 152_P3121,which is hexagonal cell.</div> <div> The scf is OK. But the band in some special k-points that is in a small range is abnormal. Almost enery bands in the same range have very low values,which are much lower than the energy of nearby k-points. There is something wrong with it. The process I calculated the band is as follows.<br> create case.klist_band file<br> x lapw1 -c -band<br> x lapwso -c<br> edit case.insp<br> x spaghetti -so<br>I have appended the values of a certain band in the case.spaghetti_ene:<br>The
