Manual detection peak

[octavianparascinet]

How can I manually detect a peak? I'm doing the manual detection on the peak detector window and when I press the "Add the manually detected peak" button it doesn't enter the list. I need to do anything else or why it doesn't work? I'm attaching a screenshot for you to see that the baseline is drawn and the peak doesn't appear on the "peak list" top left.

You can press the Peaks button in the toolbar and use the Peak Detector view, which is the old style way and may be deprecated at some point. The modern alternative is to right-click on to the chromatogram, select Peak Detector → Peak Detector UI [Direct] which shows existing peaks and also allows for manual peak detection. Both require you to hold the CTRL modifier.

Ok, thank you. It worked perfectly fine with the Detector UI (Direct), but not the old style. I have another issue about saving the detected peaks with the integration area. I don't know how to do this. Everytime I save the file in .ocb format and I open it in openchrom, it only appears the chromatogram, it doesn't show the already detected peaks nor the integration area.

Please https://lablicate.com/about/contact so we can exchange some of the problematic data as .ocb should save all the peaks.
