coefficients at the q vector #iq of the representation #irr. These files
are written by elphel and contain the quantities g_qΜ (k, i, j) <br></pre><pre><span style="font-family:arial,helvetica,sans-serif">Yes.. I am agree with you. But these are placed in elph_dir folder (which are called now as elph.inp_lambda.1 to no of q points).<br> On the other side, we will get elph.gamma.1, elph.gamma.2 and up to elph.gamma.10 after the plotband.x calculations<br>(since el_ph_nsigma = 10 for my calculation. So, elph.gamma.XX should relate to different smear values?? If so, How to we plot it??)<br></span></pre><pre><span style="font-family:arial,helvetica,sans-serif">Here I am worrying and want to know about the description of these.<br><br>Also, I too searching about the expert explanation on EL-PH calculations using PWSCF.
