Hi, Tone,<br>I have another question about 3D FFT data and 3D data of XSF file.<br>I have checked the transformation routine for <br>3D FFT data to XSF file in QE package. In that routine, final XSF grids dimension seems not the same as 3D FFT data. <br>
In fact, most situations i found the XSF grids <br>dimensions are (nx+1)x(ny+1)x(nz+1) where nx,ny,nz are 3D fft data's dimension.<br><br>I wonder about this scheme, would you please give me some hints ?<br>Regards <br>

</div>This is true, but it is also true that then you cannot display both of<br>
them simultaneously, unfortunately. Xcrysden only allows for the display<br>
of a single field at the time (i.e. the one selected in the "Datagrid"<br>
popup window).<br>
