# cif\_merge(1)

merge data values in identical data blocks of multiple CIFs. Unique data items are combined into a single data block of the output CIF; data items with equivalent values are silently merged into one. When a value differs for the same data item and the same data block in two files, a warning (error) is issued.

## NAME

cif\_merge - merge data values in identical data blocks of multiple CIFs. Unique data items are combined into a single data block of the output CIF; data items with equivalent values are silently merged into one.

## SYNOPSIS

## DESCRIPTION

Merge data values in identical data blocks of multiple CIFs. Unique data items are combined into a single data block of the output CIF; data items with equivalent values are silently merged into one. When a value differs for the same data item and the same data block in two files, a warning (error) is issued.

## OPTIONS

\--override-all\
                   Override all data items in the recipient CIF.

\--dont-override-all\
                   Do not override all data items in the recipient CIF\
                   (default).

\--override-tags  \_tag1,\_tag2\
                   Replace the values of the provided data items\

\--merge-tags  \_tag1,\_tag2\
                   Merge the values of the provided data items\

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

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

\--help, --usage\
