<div dir="ltr">Dear all,<div><br></div><div>Hi, this question might have been asked already. Please direct me to the previous post if you know of any similar issue discussed already. I tried to find, but I couldn't.</div>
<div><br></div><div>After the phonon dispersion calculation, I get the 'si.freq' and '<a href="http://si.freq.gp">si.freq.gp</a>' </div><div>I was able to plot along different directions, but how would I extract a specific phonon mode (for example, LA or TA1) from the frequency data file. I need to use only one mode of frequencies to do my calculation. Please help.</div>
<div><br></div><div>Thank you in advance,</div><div>Kyeong Park</div></div>
