PDF Subfile Restraints

The "Subfiles" page of the Restraints tab is only available if you are currently using an ICDD PDF database as reference database. Here you can select the PDF subfiles from which entries are accepted.

Select subfiles of the ICDD PDF database

If the sample can be assigned to a certain chemical context (like "mineral" or "organic" compound), it is recommended to use this information to restrict the search-match to corresponding subfiles of the PDF. The basic advantage of this limitation is the reduction of the number of candidate entries in the candidate list which makes the final selection of the matching entries by the user a lot easier.

By default, PDF entries of all subfiles are accepted. You can change this simply by marking the checkboxes of the subfiles you would like to accept. If you would like to select only a few or nearly all subfiles, you can use the Clear All or the Select All buttons at the bottom of the tabsheet.
