<DIV>Dear all, </DIV> <DIV> I calculated the phonon frequencies of FeO for a list of generic<BR> q vectors with q2r.x and matdyn.x. In the FeO.dyn files , the highest frequency is about 43 THz, while it is about 22 THz in the matdyn.modes file and FeO.freq file. What problems may occur in the the process? </DIV><p>
