.SH NAME
cif_find_duplicates \- find COD numbers for the .cif files in given directories of file lists.

.SH SYNOPSIS
cif_find_duplicates \-\-options my\-cif\-dir1/ my\-cif\-dir2/files*.cif COD\-cif\-dir/

.SH DESCRIPTION
Find COD numbers for the .cif files in given directories of file lists.

.SH OPTIONS
\-c, \-\-always\-continue
                  Continue processing and return successful return status
                  even if errors are diagnosed.

\-c\-, \-\-always\-die
                  Stop and return error status if errors are diagnosed.


\-\-max\-cell\-length\-difference 0.5
                  Maximum difference of unit cell lengths allowed for
                  entries regarded as the same, in angstroms
                  (default: 0.5).


\-\-max\-cell\-angle\-difference 1.2
                  Maximum difference of unit cell angles allowed for
                  entries regarded as the same, in angstroms
                  (default: 1.2).


\-\-check\-bibliography
                  Only CIFs that have different bibliography data are
                  declared different if all other parameters match.
                  CIFs with missing bibliographies are assumed to have
                  matching bibliographies (default).

\-\-no\-check\-bibliography, \-\-dont\-check\-bibliography
                  Ignore bibliographic data of all CIFs; thus even files
                  with different bibliographies will be regarded the same
                  if their cells, chemical formulae and measurement
                  conditions match.


\-\-use\-sigma, \-\-dont\-ignore\-sigma, \-\-no\-ignore\-sigma
                  Use standard deviations (sigmas) when comparing unit
                  cell constants (default).

\-\-no\-use\-sigma, \-\-dont\-use\-sigma, \-\-ignore\-sigma
                  Ignore standard uncertainties (sigmas) when comparing
                  unit cell constants.


\-\-check\-sample\-history
                  Only CIFs that have different sample history data
                  (as recorded in the _exptl_crystal_thermal_history
                  and _exptl_crystal_pressure_history tags) are declared
                  different if all other parameters match.

\-\-no\-check\-sample\-history,

\-\-dont\-check\-sample\-history,

\-\-disregard\-sample\-history
                  Ignore sample history of all CIFs; thus even files
                  with different sample histories will be regarded the
                  same if their cells, chemical formulae and measurement
                  conditions match (default).


\-\-use\-attached\-hydrogens
                  Include the number of implicit hydrogen atoms
                  when calculating the summary chemical formula.
                  Implicit hydrogen atoms are specified using
                  the _atom_site_attached_hydrogens data item.

\-\-no\-use\-attached\-hydrogens,

\-\-ignore\-attached\-hydrogens
                  Ignore the number of implicit hydrogen atoms
                  when calculating the summary chemical formula.
                  Implicit hydrogen atoms are specified using
                  the _atom_site_attached_hydrogens data item
                  (default).


\-\-continue\-on\-errors
                  Do not terminate script if errors are raised.

\-\-die\-on\-errors, \-\-dont\-continue\-on\-errors,

\-\-do\-not\-continue\-on\-errors, \-\-no\-continue\-on\-errors
                  Terminate script immediately if errors are raised (default).

\-\-continue\-on\-warnings
                  Do not terminate script if warnings are raised (default).

\-\-die\-on\-warnings
                  Terminate script immediately if warnings are raised.

\-\-continue\-on\-notes
                  Do not terminate script if notes are raised (default).

\-\-die\-on\-notes
                  Terminate script immediately if notes are raised.


\-\-use\-perl\-parser
                  Use Perl parser to parse CIF files.

\-\-use\-c\-parser
                  Use C parser to parse CIF files (default).


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

\-\-version
                  Output version information and exit.
