<div><p>Dear QEers:</p><p> Sorting phonons by magnitude and band index are two ways to plot phonon dispersions. Especially, the later is important for the precise understanding of phonons and for the calculation of some physical parameters, like Gruneissen constants. I have written a small code (named sort_phon) to do these sorting tasks, which needs the output of Quantum ESPRESSO (matdyn.modes) as input. The code package can be download in the link below: </p><p>http://bbs.sciencenet.cn/home.php?mod=space&uid=345795&do=blog&quickforward=1&id=422819</p><p>where an introductory tutorial and an example about graphene phonon dispersions is included.</p><p>I sincerely hope it could bring you some convenience in your daily research.</p><p>Best Wishes!</p><p>Yours Sincerely</p><p>L.
