Reference Database Library

Match! is capable of handling more than a single reference pattern database at a time: You can switch between all reference databases you have created (i.e. created index files for) while keeping your diffraction data in memory, thus enabling you to compare phase identification results from various reference databases. Of course, it is not necessary to perform a re-indexation of a reference database when switching between them!

The reference databases are handled in the so-called "Reference Database Library". This dialog is opened automatically if you did not install a reference database along with Match!; it can also be opened by selecting the "Select Reference Database" command from the "Database" menu, or by pressing the corresponding button in the toolbar.

The "Reference Database Library" contains a list (in fact two lists) of all reference databases that are available for the current user (see below). For each available reference database, the name, the number of entries, and the directory in which it is stored are displayed. There are two lists of reference databases, one for reference databases that are available to all users (the upper list), and another one that can only be accessed by the current user below. The database you are currently using is identified by an ">>>" arrow to its left.

On a multi-user machine (e.g. using Windows XP, Vista or Windows 7/8), each user may have individual reference database(s). It is perfectly possible to create a new reference database as a normal (standard) user, i.e. it is not necessary to have administrator privileges for this task. However, please note that a standard user can create reference databases only for himself, while an administrator can create databases for all users. If a database is available to all users, this is indicated by a '*' sign in the column "All". Note that databases with this mark cannot be modified or deleted by normal (standard) users!

You can manage your reference databases using the six buttons at the bottom of the "Reference Database Library" dialog:
