Info

3. Click the name of the library. The spectra contained in the library are listed at the right side of the tab. 4. Choose Delete. A message asks whether to delete the library. 5. Choose OK. The library is deleted. Note If the library file is specified in Windows as read-only, it cannot be deleted until you remove that specification. See the Windows Help system for information on changing the attributes or properties of files (search for the word “attributes” or “properties” to locate the relevant topics). ▲ 6. Choose Close to close Library Manager if desired. Searching a library for text Click the Search For Text tab if you want to find library spectra by searching for text in specified information fields saved with the spectra. For example, you can search for spectra whose information contains a specific name or the date the spectrum was collected. The available fields depend on the information included with the library. You can print information contained on the tab by using Print in the File menu. 280 Thermo Nicolet
Follow these steps to search for text: 1. Choose Library Manager from the Analyze menu. Library Manager appears with the Library Names tab in front. 2. Click the book that contains the library you want to search. 3. Click the name of the library. The spectra contained in the library are listed at the right side of the tab. 4. Click the Search For Text tab. The name of the selected library is shown near the top of the tab. 5. If you want to search only this library, select This Library. If you want to search all the libraries, select All Libraries. If you want to search a different library by itself, select it on the Library Names tab and then return to this tab and select This Library. 6. Specify whether to search for text in one field or in all fields by selecting an option from the Field To Search drop-down list box. The available fields depend on the information included with the library. If you selected All Libraries, only the All Fields, Compound Name and Index # fields are available. 7. Type the text to search for in the Text In Selected Item box. 8. To search all spectra, select All Dates. To search only spectra collected before a certain date, select Before and enter the date in the corresponding text box. The options in the Date Entered box let you limit the search to spectra collected during a specified time period. Express dates on this tab in the format used by your system. For example, in the U.S.A. this is normally month/day/year, with the month and day as twodigit numbers and the year as a four-digit number. To search only spectra collected after a certain date, select After and enter the date in the text box. To search only spectra collected during a certain period, select From __ To __ and enter the starting and ending dates. Note Libraries created using versions of OMNIC before OMNIC E.S.P. do not have date fields. Spectra in these libraries will be found only if you select the All Dates option. ▲ OMNIC User’s <strong>Guide</strong> 281
