Preventing the overwriting of files Note Turn on Prevent Overwriting Of Files to ensure that existing files are not overwritten when you save a spectrum, configuration, experiment or option file. If you attempt to save a file using the same filename as an existing file, a message informs you that the file cannot be overwritten. Choose OK to close the message and then save the file using a different filename. If the When Saving A Spectrum Or Spectral Group option is turned on in the Require Digital Signatures box, you will be prompted to enter a user name and password when you save a spectrum, regardless of the setting of Prevent Overwriting Of Files. ▲ Saving the interferograms with collected spectra Turn on Always Archive Original Data to save the interferograms with spectra you collect and save. The interferograms are saved regardless of the setting of Save Interferograms on the Collect tab of the Experiment Setup dialog box. Requiring digital signatures Use the options in the Require Digital Signatures box to require that users provide a digital signature when saving spectral data, an experiment or a configuration or when adding a report to a report notebook. The visible portion of a digital signature consists of a user name, a date and a stated reason for signing. A digital signature also contains encrypted information that guarantees that the file has not changed since it was signed and that the file can be changed only by a user who enters the correct name and password. Displaying the Security tab Important Note Turn on Show Security Options In This Configuration to include the Security tab when you view the options. This option is turned on by default. If you want to set OMNIC so that other users will not have access to the Security options, turn this option off and then save the configuration using a new filename. If you turn this option off, do not overwrite default.con or OMNICadministrator.con when you save the configuration. ▲ To avoid accidentally overwriting configuration files, turn on Prevent Overwriting Of Files on the Security tab. This option requires you to use a different name when saving a configuration file. ▲ Specifying the default configuration location Use the Browse button in the Options For All Configurations box to specify the directory location of the configuration files that you will assign to users as their default configurations. When you choose Browse, the Open dialog box appears. Locate and select the desired directory and then choose Open. The path appears to the right of Default Configuration Path. Set the options 1. Choose Options from the Edit menu. The Options dialog box appears. 2. Display the set of options you want to change by clicking the appropriate tab at the top of the dialog box. 102 Thermo Nicolet
3. Set the options as desired. 4. Repeat steps 2 and 3 for the other options you want to change. 5. When you are finished setting the options, choose OK. Customizing a menu The Edit Menu command in the Edit menu allows you and other users to customize the contents of the OMNIC menus for the way each person prefers to use the software. You can enable, disable, hide, add, delete and modify items in the menus. Note You can disable, but not hide, commands in cascading menus. These menus appear when you point to items in the Help menu that have an arrow symbol to the right of the item name. ▲ After you customize the menus, you can save your menu configuration in a configuration file that can be opened later. This lets you quickly reset OMNIC to your preferences after others have used the software. You can assign a password to protect the file so that only you can make changes to the configuration. See “Saving a configuration” and “Opening a configuration” in the “File” chapter for more information. Note You can hide all of the menus by turning on Hide All OMNIC Menus in the Edit Toolbar dialog box. See “Customizing a toolbar” for details. ▲ Customize menus 1. Choose Edit Menu from the Edit menu. The Edit Menu dialog box lists every item in each OMNIC menu and the current state of each item. The scroll bar to the right of the columns lets you scroll through the menus and menu items. The following table describes the three possible states of any item.
