I thing some thing is happening in a unusual way so any one can help?<br><br></div>The procedure which i follow.<br><br></div>makestruct..<br></div>cp init.struct BP.struct<br></div>init_lapw<br>phonopy --wien2k -c BP.struct -d --dim="2 2 2" <br></div><span style="font-size:12.8px"> at this steps the erorrs looks like...</span><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px"><br></span></div><div>_ __ | |__ ___ _ __ ___ _ __ _ _ <br> | '_ \| '_ \ / _ \| '_ \ / _ \ | '_ \| | | |<br> | |_) | | | | (_) | | | | (_) || |_) | |_| |<br> | .__/|_| |_|\___/|_| |_|\___(_) .__/ \__, |<br> |_| |_| |___/<br> 1.10.0<br><br>Python version 2.7.11<br>Creating displacements<br>Settings:<br> Supercell: [2 2 2]<br>Spacegroup: C2/m (12)<br>Number of non-equivalent atoms in BP.structS-001: 80<br>Number of non-equivalent atoms in BP.structS-002: 80<br>Number of non-equivalent atoms in BP.structS-003: 52<br>Number of non-equivalent atoms in BP.structS-004: 52<br>Number of non-equivalent atoms in BP.structS-005: 80<br>Number of non-equivalent atoms in BP.structS-006: 52<br>Number of non-equivalent atoms in BP.structS-007: 80<br>Number of non-equivalent atoms in BP.structS-008: 52<br>Number of non-equivalent atoms in BP.structS-009: 80<br>Number of non-equivalent atoms in BP.structS-010: 80<br>Number of non-equivalent atoms in BP.structS-011: 52<br>Number of non-equivalent atoms in BP.structS-012: 52<br>Number of non-equivalent atoms in BP.structS-013: 80<br>Number of non-equivalent atoms in BP.structS-014: 80<br>Number of non-equivalent atoms in BP.structS-015: 80<br>Number of non-equivalent atoms in BP.structS-016: 80<br>Number of non-equivalent atoms in BP.structS-017: 80<br>Number of non-equivalent atoms in BP.structS-018: 80<br><br>disp.yaml and supercells have been created.<br> _ <br> ___ _ __ __| |<br> / _ \ '_ \ / _` |<br> | __/ | | | (_| |<br> \___|_| |_|\__,_|<span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px"><br clear="all"></span><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">Thanks & Regards<div>Rajneesh Chaurasiya</div><div>Junior Research Fellow</div><div>IIT,Jodhpur, India<br></div><div>Mob.
