Dear Li MingkaiThe practical solution for your problem is to set verbosity = 'high' in your control card, change ibrav to "1", ignore CELL_PARAMETERS card, then do your calculation.look at the head of your output file, then copy and paste the new CELL_PARAMETERS and atomic positions for ibrav=0 and redo your calculation.

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. -- Mingkai Li ============================== ========================= School of Material Science and EngineeringHubei UniversityWuhan, Hubei ProvinceP.
