Are the q points generated by the ph.x and kpoints.x different even when you<br>
use the same grid index ?<br>
If so, kpoints.x cannot be used.<br>
<br>

Dear Mitsuaki,<br>
<br>
Thanks for your reply. I just want to add more question regards the points<br>
produced by kpoints.x needed for the lambda.x execution. I have some q grids<br>
that have 7, 13 ,21 or even 43 points . How can I produce 7, 13, 21 and 43<br>
points using kpoints.x ? Is it legitimate to say , in the case of 7, produce<br>
9 points and take off two of them?<br>
<br>
Once again, thanks in advance.<br>
<br>
<br>

Dear Elio<br>
<br>
Hello,<br>
1- lambda(w) (The integration of alpha2F) is not computed in matdyn.x.<br>
Please integrate alpha2F(w) manually.<br>
<br>
2- To plot it with gnuplot, you have to modify that file as each frequency<br>
has single line.<br>
For plotting it with gnuplot, you have to modify that file to write each<br>
frequency in a single line.<br>
That file format will be changed in the next release.<br>
<br>
Best regards,<br>

Subject: [QE-users] alpha^2F (w) and lambda (w)<br>
<br>
Dear all, I am trying to plot The Eliashberg function and the electron<br>
phonon parameter in terms of the frequencies. I know that matdyn.x produces<br>
these two files and that alpha^2F data is found in a2FDos.X files . <br>
<br>
1- Where can I find the lambda (w) information?<br>
<br>
2- How can I plot these graphs? The file is not suitable to be plot in<br>
gnuplot.<br>
<br>
Any help would be appreciated. Thanks<br>
<br>
