Dear Ryky,<br>
<br>
G vectors are stored in the $prefix.save directory when the wf_collect<br>
flag (CONTROL namelist of pw.x) is set to .TRUE.<br>
<br>
at the end of the calculation you'll find<br>
$prefix.save/gvectors.dat<br>
$prefix.save/K00001/gkvectors.dat<br>
and similarly for each k point.<br>
<br>
$prefix.save/gvectors.dat contains the G vector components for all vectors used to represent the density.<br>
<br>
for each kpt, $prefix.save/K00001/gkvectors.dat contains the G vectors used to represent the corresponding wfcs (all the G vectors in the k+G cutoff sphere)<br>
<br>
these are stored both as a map wrt the density G vectors (INDEX tag) as well as 3D integer components in crystal (reciprocal) units (GRID tag)<br>
<br>
Note that all gvectors.dat and gkvectors.dat files are binary.<br>
In order to inspect them it is convenient to convert them to xml<br>
by doing<br>
<br>
~espresso/bin/iotk convert gvectors.dat gvectors.xml<br>
<br>
hopt this helps<br>

I was wondering if Quantum Espresso outputs G-vectors which are associated with the plane-waves stored in the wfc file. Could<br>
someone tell me where to look at this G-vectors list?<br>
<br>
Thank you!<br>
