Hi<br><br>Could we do all-electron relaxation or variable-cell relaxation by QE ?<br>Using pw.x we need to specify pseudo-potentials but we are going to do all-electron relaxation and letting core electrons to be optimized the same as valence ones. We appreciate any comment and help to do it in advance. <br clear="all">
