Search Setup

Configure settings for correlation search and multi-component search using Search Setup. These settings are used automatically when you select Correlation Search or Multi-component Search from the Identify menu in the desktop interface or from the main menu in the touchscreen interface.

Using the desktop interface, you can also use Search Setup to specify the location of additional libraries on your system. See "Add Library Locations" for details.

Correlation search settings

A correlation search compares your measurement to compounds in your libraries and returns the closest matches. The results include the match value for each compound with a value between 0 and 100, with 100 indicating a perfect match

Correlation search settings

Setting Description
Match historical search results

Select to have search results match those of legacy OMNIC applications.
The improved algorithm used in OMNIC Paradigm software scales large peaks to reduce the effects of totally absorbing spectra.

Select only if you are comparing new measurements with older data collected using legacy OMNIC software.

Maximum spectra in search results

Limit the number of search results. For example, with a maximum of 5, the search will return only the 5 best matches.

You can enter a value from 1 to 20.

Show compounds with match values above ____

Set a threshold for which matches are returned by the search. For example, with a value of 60, the correlation search will return only matches with a match value above 60.

Search all libraries

Select to search all of your libraries. Clear the selection to specify only specific libraries to use for the search.

Use full spectral range

Select to use the full spectral range for the search. Clear the selection to specify one or more limited ranges for the search.

You can use multiple regions to exclude another region from the search. For example, include a region on either side of a totally absorbing peak to exclude it from the search.

Multi-component search settings

Use multi-component search to identify the components making up your sample.
