You can overlay Chenomx spectra (.cnx
) in any
module with a Spectrum View. Overlaying a spectrum in Compound Builder or
Spin Simulator can aid the compound signature creation process,
while overlays in Profiler and Processor can provide useful visual
references to other spectra in a dataset.
How do I overlay a spectrum in Compound Builder and Spin Simulator?
-
Click Set Spectrum Overlay.
-
Locate the folder containing the spectra that you would like to overlay, and select the spectra.
-
Click OK.
How do I overlay multiple spectra in Profiler and Processor?
-
Click Tools > Add Spectrum Overlays.
-
Choose whether to Add Files or Add Folder
-
Locate the files or single folder containing the spectra that you would like to overlay.
-
Select whether to color all overlays as a default grey color, or whether to automatically assign different colors to each overlay using the radio buttons.
-
Click OK.
How do I remove a single spectrum overlay?
-
In the Legend view of the Sidebar, click the X beside the overlay that you would like to remove.
How do I remove all spectrum overlays in Profiler and Processor?
-
Click Tools > Remove Spectrum Overlays.
How do I automatically set the overlay colors?
-
Click the Automatic Coloring (
) icon in the Legend Sidebar panel.
This will assign a different color to each spectrum overlay. Clicking it again will set all overlays back to the default color.
How do I stack overlaid spectra in Profiler or Processor?
-
Click the Stack Spectrum Overlays... menu item in the Tools menu.
This will open a dialog for you to input the height of all overlays.
-
Or you can use the stack overlay widget on the left hand side of the graph to manually adjust the stack height.
Tips and Tricks
-
You can also remove all spectrum overlays by clicking on the X beside the Overlay Lines section in the Legend.
-
You can only overlay spectra in the Chenomx NMR Suite format (
.cnx
). If the spectrum you would like to use is in a different, supported format, you need to import and save it in Processor before using it as an overlay. -
In Compound Builder and Spin Simulator, you can only have one spectrum overlay at a time. In Profiler and Processor, you can have up to fifty spectrum overlays.
-
In Compound Builder, if you overlay a spectrum whose frequency does not match the magnet frequency specified in the Compound Details, you are notified of the mismatch, and given the chance to update the Compound Details to match the spectrum overlay.
-
Profiler and Compound Builder also give the possibility to ovelay the sum or subtraction lines from different Chenomx spectra. These functionalities are available from the Tools menu.
