[Pw_forum] cif2qe problem of conversion

[moury at mpi-muelheim.mpg.de]

Dear users,

 

I would like to convert a cif file to a QE file using cif2qe.sh shell,
nevertheless I have a problem in the conversion, I have no ATOMIC_POSITIONS
in my output file (see below).

 

I am using espresso-5.1.1 with GNU Awk 4.0.1, and bash version 4.3.11

 

I run the code with ./cif2qe.sh (-i or –s or nothing) myfilecif

 

Here is my cif:

 

_symmetry_cell_setting               'Cubic'

_symmetry_Int_Tables_nummber         218

_symmetry_space_group_name_H-M       'P -43n'

_symmetry_space_group_name_Hall      'P -4n 2 3'

_cell_length_a                       15.2916(3)

_cell_length_b                       15.2916(3)

_cell_length_c                       15.2916(3)

_cell_angle_alpha                    90.00000

_cell_angle_beta                     90.00000

_cell_angle_gamma                    90.00000

I obtain the following output:

Any idea ???

 

I have exactly the same problem with other files.

 

Thank you very much for your help.
