Dear all:<div> I run ph.x (PHonon-5.0) with the error below:</div><div><div><i>" from set_irr_sym : error # 811</i></div><div><i> wrong representation "</i></div><div><br></div><div> I followed the instruction at here (<a href="http://qe-forge.org/pipermail/pw_forum/2012-July/099123.html" target="_blank">http://qe-forge.org/pipermail/pw_forum/2012-July/099123.html</a>) and changed the 258 line in PH/set_irr.f90 to "<i>(ABS(eigen(imode)) + ABS (eigen (jmode) )) < 1.d0) ) THEN</i>". </div>
<div> But my computation failed.</div><div> Can you give me any suggestion?</div><div> Thanks in advance :)</div><div> </div><div> The following is my input file:</div><div> SCF calulation:</div>
