Using this dialog/command you can quickly add a new entry to the current reference database, e.g. by importing data from a cif-file. If the current anchor pattern (bottom-most experimental pattern) contains peak data, they will be copied to the new entry automatically.
You can open the "Add New Entry Data" dialog either using the corresponding command from the "Database" menu or by pressing the keyboard shortcut <Ctrl+Shift+A>.
Once the "Add New Entry Data" dialog is displayed, you can enter the information to be stored the new entry. Please note that entering the Formula sum on the "General" tab is mandatory; we recommend to at least also enter the Chemical name and/or the Mineral name information, because they will be displayed in the "Candidate phase" column in the Candidate list later on.
The easiest way to enter the new entry data is to import them from a cif-file. In order to do so, please click the corresponding button in the top right corner of the dialog, select the cif-file and finally press "Open". The entry data will be imported from the cif-file and displayed in the corresponding dialog elements afterwards.
When entering the new entry data you should step through the tabs in the "Add New Entry Data" dialog one by one:
The four database fields at the top of the "General" tabsheet grouped as "Phase Description" are used later on to identify a certain entry in the Candidate list, so it is worth while to enter reasonable data here. As has already been mentioned, the Chemical name and/or the Mineral name information will be displayed in the "Candidate phase" column in the Candidate list later on.
Note: When you enter the formula sum in the corresponding field on the "General" tabsheet, please keep in mind that it is important to use upper and lower case characters in the element symbols, like in "Ca Si O3" (do not use "ca si o3" or "CA SI O3"). We also recommend to insert a blank character between the elements according to the CIF- or PDF-standard. Hence, please enter e.g. "Cu S O4 (H2 O)5" (and not "CuSO4(H2O)5).
You can add a quality qualifier in the lower left corner if you can estimate the quality of your diffraction data (e.g. 'C' if they are calculated).
If you do not have a diffraction pattern but rather crystal structure data, you can enter them on this tabsheet so that the diffraction pattern can be calculated by Match!. The first thing you have to enter is the crystal system in the upper left corner. Once you have selected a crystal system, the "space group" combobox below will be filled with appropriate space groups, so that you can select your space group afterwards.
Once you have selected crystal system and space group, you can enter the unit cell constants. Depending on the crystal system and space group selection, only a few parameters have to be entered.
You are now ready to enter the atomic parameters: Please click in the atomic parameter table to the right in the first line directly below "Element", enter the first element and press <Tab>. The cursor will advance to the next field "X". Enter the coordinate x of the first atom, press <Tab>, enter y, press <Tab> again, and finally enter z. If there is any information given about the isotropic displacement factor Bi and the site occupation factor "Occ.", you can enter them in the corresponding remaining two columns; otherwise, please press <Tab> until the cursor has advanced to the next line. Once you have entered all atomic coordinates given in the described manner, you should press the <Return> button on your keyboard to finish the input of the atomic parameters.
There are four alternate ways in which this tabsheet can be filled:
Copy of current peak listIf the current anchor pattern (bottom-most experimental pattern) contains peak data, they will be copied to the new entry automatically.
Calculation of diffraction pattern from crystal structure dataIf a complete set of crystal structure information is present on the "Crystal structure" tabsheet (e.g. imported from a cif-file), Match! will automatically calculate the diffraction pattern from the given crystal structure data when you open the "Diffraction pattern" tabsheet. After a few seconds, the diffraction pattern will be displayed. Of course, you can also (re-)calculate the diffraction pattern by clicking on the corresponding button.
Import of diffraction patternIf you have a peak data file (Stoe (*.pks), Philips PANalytical (*.udi) or Endeavour (*.dif)) available, you can import it by clicking on the "Import" button to the left of the peak data table.
Manual input of diffraction dataIn order to enter the diffraction pattern (peak data) manually, you should first check the appropriate settings of the "Radiation wavelength" and "Abscissa" fields on the upper left hand side of the tabsheet. Afterwards, click on the "Add" button below the table to the right. Now enter the 2theta value (or d-value, depending on "Abscissa") of the first peak, then press <Tab> to advance to the second column and enter the corresponding intensity. Finally, press <Return> or <Tab> again in order to finish the input of the first peak; the peak will appear in the diffraction pattern to the left of the table. Continue entering the remaining peak data in a similar manner until you have finished.
On the final tabsheet, both physical property data (density, color) and bibliographic information can be entered. If a complete set of crystal structure data is present on the corresponding tabsheet, you can (re-)calculate the density (which is an additional useful information for qualitative phase analysis) simply by clicking on the "Calculate pattern" button on the "Diffraction pattern" tabsheet. We also strongly recommend to enter measured density and color if available.
Below, you can enter the bibliographic details, e.g. if the entry data originate from a scientific paper. When you enter the journal name, your input will be automatically expanded to the next matching journal name in the internal CODEN table. At the same time, the CODEN will be automatically set. This works also the other way round: If you know the CODEN for the journal, you can select it in the corresponding combobox in the lower left corner; the corresponding journal name will be set automatically.
Once you finished editing the new entry data, please press "OK". After a few seconds, a message will be displayed indicating that the new entry has been added to the current reference database.
