Dear Zahra,<br>
<br>
the pw_export format is read eg in WanT (<a href="http://www.wannier-transport.org" rel="noreferrer" target="_blank">www.wannier-transport.org</a>).<br>
If you download any recent version, and grep for routine starting with<br>
<br>
qexpt_ in want/src/wannier/*f90<br>
<br>
you'll see how grids are read (in particular see ggrids.f90 and wfc_data.f90)<br>
<br>
Sources of the qexpt library (readin pw_export data) can be found in<br>
want/src/baselib/qexpt.f90<br>
<br>
hope it helps<br>

I used pw_export to obtain wavefunction. The coefficients of wavefunctions in k-space were written in wfc.* files.<br>
<br>
But I'm confused about grid.* files. In fact I want to find the G vectors ( of grid.* files) that the wavefunction<br>
coefficients are written corresponding them.<br>
<br>
I will be very appreciated if any one can explain more about them.<br>
