But it seemed that the pw.x tried to find some symmetry and got wrong number of symmetries. I tried nosym, nosym_vec, no_inv. Nothing works. I tried old version down to 5.0, which worked. After version 5.1, the error emergied. Of course, I tried to use celldm(1)~(6). It works well for all version. Since this input file is generated by a script automatically. I don't tend to modify the script a lot and try to figure out what happened before change everything. </div><span class="yiv8885435572HOEnZb"><font color="#888888"></font></span><div><br clear="none"></div>-- <br clear="none"><div class="yiv8885435572m_-4614469622381240043gmail_signature">Mingkai Li<br clear="none">============================== =========================<br clear="none">School of Material Science and Engineering</div><div class="yiv8885435572m_-4614469622381240043gmail_signature">Hubei University</div><div class="yiv8885435572m_-4614469622381240043gmail_signature">Wuhan, Hubei Province</div><div class="yiv8885435572m_-4614469622381240043gmail_signature">P.
