.TH CIF_REDUCE_NIGGLI 1 .SH NAME cif_reduce_Niggli \- perform Niggli cell reduction of CIF files. .SH SYNOPSIS cif_reduce_Niggli \-\-options input1.cif input*.cif .SH DESCRIPTION Perform Niggli cell reduction of CIF files. .SH OPTIONS \-\-use\-perl\-parser Use Perl parser for CIF parsing. \-\-use\-c\-parser Use Perl & C parser for CIF parsing. \-\-compute\-symops Apply basis change to symmetry operators. Not all lattices are processed correctly, thus this option is experimental only and is turned off by default. \-\-debug, \-\-no\-debug Turn on/off the debug prints of reduction algorithm. Default: off. \-\-help, \-\-usage Output a short usage message (this message) and exit. \-\-version Output version information and exit. .SH "REPORTING BUGS" Report cif_reduce_Niggli bugs using e\-mail: cod\-bugs@ibt.lt
