Dear abinit user,
Aiming to establish the phonon dispersion curves of ZnSe in cinnabar structure. First I tried to make the K-points convergence test.
But surprisingly, the code couldn't recognize the cinnabar spacegroup and instead he gives in the output file :
 space group P1 (#  1); Bravais aP (primitive triclinic)  
while in fact the cinnabar is of Space Group: P3₂21 and No: 154 
I am quiet a beginner in using abinit, I welcome any suggestions  to correct my input file (especially the quick ones!!!!)
The outputfile is attached,  please  see down my input file:
