Application Layout
The application layout consists of several parts. Beside common parts like toolbar with selected features or statusbar showing current document information, main part is the document frame. On left hand side there is a Peaklist Panel - a list of all labeled peaks with values of m/z, intensities and annotations. Rest of the document frame covers currently active module with corresponding control panel on right hand side. In some cases, it can be very helpful to switch the document window to horizontal mode, with the peaklist panel bottom [Config → Peaklist Bottom] or to remove the panel completely [Config → Show Peaklist]
to see the module frame only.
