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 style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">After the phonon dispersion calculation, I get the 'si.freq' and '<a href="http://si.freq.gp/" target="_blank">si.freq.gp</a>' </div>
<div style="font-family:arial,sans-serif;font-size:13px">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>
