A dialog appears to inform you that perspectives and views are switched automatically. OpenChrom selects the best perspective and views for your to display the data in an optimal way. Please disable the checkbox if you don’t like OpenChrom to do this for you. After peak detection, the “Chromatogram Peaks” perspective is shown.

Afterwards, run the peak integrator (Menu > Chromatogram > Integrators > Integrator Trapezoid > Peak Integrator). Peak detection and integration are separated in OpenChrom. This offers a greater flexibility to analyze chromatograms.

All detected peaks are marked with an inverse triangle in the chromatogram editor.
