<br>
<br><font size=2 face="sans-serif">I enclose the file, that is the exact
file provided in the downloaded package to run the example (14 in versin
4.2.1), with only a small modification.</font>
<br><font size=2 face="sans-serif">Indeed, as you will see, I just substitute
the X-points coordinates by some other coordinates, for the d3.x (line
199) and the phonon calculation (line 181).</font>
<br><font size=2 face="sans-serif">Or perhaps this is only why I think
I am doing...</font>
<br>
<br><font size=2 face="sans-serif">Once again, I have no trumble at all
to run it on k-points belonging to high symmetry axis (1,0,0 0.5,0.5,0.5,
0.2,0.2,0.2 0.3,0.3,0 ....).</font>
<br><font size=2 face="sans-serif">The k-point here in the file is 0.3,0.2,0.1.</font>

Dear Hugo,<br>
the d3.x calculation has to be done following a strict order. Did you precede
the d3.x calculation with a phonon calculation at the same point? With
the same prefix and outdir?<br>
<br>
Anyway, please send me the three inputs (pw, ph, d3) as well as any script
you are using to run them and I'll try to reproduce your problem: without
it is impossible to say anything definitive.<br>
<br>
cheers<br>
