Space group determination and data statistics (XPREP)

Correct assignment of the space group is a prerequisite for structure solution and refinement.

XPREP is the highly-advanced engine for

• unambiguous space group determination
• and data handling.

It has all required tools built in, including merging data from various data sets, statistical analysis. XPREP displays the calculated Patterson sections, de-twinning of merohedral crystals.

Apart from the robust and reliable space group determination using a combination of lattice exceptions, systematic absences and statistics to propose the correct space group – extensive data statistics and setup of files for structure solution are also provided.
