Re: Filtering an area
For quantification, if each compound has some distinct ions, you may specify a quantifier and a response factor to calculate the total response. If there are no distinct ions, you may need to adjust areas to be tight around peaks. Alternatively, you may detect peaks on SIC manually or use the Proces...

Re: 50% peak widths or average 4δ peak width
Size I(50) is the Column 1 peak width at 50% peak height Size II(50) is the Column 2 peak width at 50% peak height There is no peak width computed based on standard deviation. Assuming all peaks are Gaussian, you may derive the relative peak height. For example, the following post shows that +/- 2δ...

Re: Undesired compounds
Depending on how undesired compounds mix with others, you may be able to add a polygon to subdivide the region or exclude the blobs of these compounds.

Re: Identification of peaks in Image investigator
If you generated a feature template, make sure to choose Areas to be analyzed by Compound Finder. Also, check if the chromatograms are well covered by the feature areas. If you get fewer unique compounds than expected, try to turn off some checks. For example, If spectra are available, try only the ...

Re: Blob Detection on SIC (or CLIC)
You can perform local blob detection on SIC or CLIC. If you want to detect all peaks in a region, create and select a rectangle to cover the region on a SIC > Edit > Local Blob Detection.

Re: Command Line Import
Besides what described in User Guide, there are other hidden arguments. We didn't publish them because they are not polished for general usage. But, if you encounter any use case that CLI does not seem to work, just ask us.
