When I change the line broadening for a spectrum in Processor, then take the spectrum back to Profiler, the library signatures do not seem to reflect the new line broadening. What is happening?

The CSI lineshape is the key to matching library signatures to patterns in your experimental spectrum. The more closely your CSI settings in Processor match a spectrum, the better the library compounds will match while profiling the spectrum.
Specifically, when you make changes to your spectrum in Processor (like adding or changing line broadening), you need to update your CSI settings to reflect the changes. If you are using DSS or TSP as a CSI, you can usually just switch to the CSI Editor in Processor and click ‘Find Automatically’. If the automatic method does not work, simply adjust the red CSI peak to better fit the spectrum, exactly as you would adjust peaks and clusters in other modules.
