# cif\_find\_symmetry(1)

find the symmetry of the atoms in the unit cell of a CIF crystal structure. In order to obtain correct results most of the time, all atoms of the unit cell should be present in the input. This can be achieved by using cif\_p1 or similar programs.

## NAME

cif\_find\_symmetry - find the symmetry of the atoms in the unit cell of a CIF crystal structure. In order to obtain correct results most of the time, all atoms of the unit cell should be present in the input. This can be achieved by using cif\_p1 or similar programs.

## SYNOPSIS

cif\_find\_symmetry --options input1.cif input\*.cif

## DESCRIPTION

Find the symmetry of the atoms in the unit cell of a CIF crystal structure. In order to obtain correct results most of the time, all atoms of the unit cell should be present in the input. This can be achieved by using cif\_p1 or similar programs.

## OPTIONS

\--precision  1e-5,

\--symmetry-precision  1e-5\
                   Tolerance of distance between atomic positions and between\
                   lengths of lattice vectors to be tolerated in the symmetry\
                   finding (default: 1e-5).

\--use-spglib\
                   Use spglib for symmetry search. Currently, spglib is\
                   the only implemented method.

\-F, --float-format "%.12g"\
                   Specify format to print out floating point numbers.

\--dump-symmetry-dataset\
                   Suppress regular output and dump symmetry data structure,\
                   as returned from spglib.

\--dont-dump-symmetry-dataset,

\--no-dump-symmetry-dataset\
                   Produce regular output.

\--use-perl-parser\
                   Use Perl parser for CIF parsing.

\--use-c-parser\
                   Use Perl & C parser for CIF parsing (default).

\--help, --usage\
                   Output a short usage message (this message) and exit.

\--version\
                   Output version information and exit.
