The menu has at the top a selection box, where you can switch between the different lipid classes. Then a table follows, whereupon the name of the analyte is in the first column and the area in the second. The display name consists in principle of “$name$:$double_bonds$” (e.g. 50:2). If there exists more than one adduct/modification, the modification name is added with _$modification_name$ (e.g. 50:2_NH4). At the bottom of the menu, the range for the 3D viewer can be set. The current center m/z value of the extraction is displayed in the 2D viewer (see 3D viewer ). After the m/z range has been changed, the “Update” button has to be pressed to change the display. The “Show 2D-View” select box can fade out the 2D viewer.
If a row of the table is clicked the peaks are displayed in the 3D and the chromatogram viewer. If the row is clicked with the right mouse button a popup appears:
This allows to add an additional analyte or to delete the selected one. To delete several analytes at once, keep Ctrl or Shift pressed and select the analytes, this will prevent refreshing of the 3D viewer and save time. As soon as you release Ctrl or Shift, the 3D viewer will be refreshed by the analyte that was selected at last. Before/after just determines the position where the analyte will be added. The adding of a new analyte requires the name of the analyte, its chemical formula, the name and the formula of the modification if any, the m/z tolerance of the chromatogram and the exact mass.
