Isotopic Distribution Panel
Insert the peptide sequences of the peptides to calculate the isotopic distribution for, and select the charge
and the number of neutrons to add, e.g., for SILAC labelling, for each peptide. The isotopic distribution will
then be displayed for each peptide, both in a table and as a spectrum.
- Zoom In: Left Click and drag in the spectrum to select a m/z interval to zoom in on.
- Undo Zoom: Right Click to zooms out to the complete distribution.
- Show Peak Details: Hold the cursor over a peak to display the x- and y-values for that peak.
- Peak Picking: Left Click on a peak to start peak picking. Move the cursor to another peak,
to display the m/z distance between the peaks. If the distance matches the mass of an amino acid or a modified
amino acid, this will be displayed in the spectrum. Left Click on the second peak to lock the distance and
enable peak picking to continue from the last selected peak.
- Remove Peak Picking: Ctrl + Left Click removes the primary peak picking.
- Store Peak Picking: Alt + Left Click holds the primary peak picking in a red font and starts a secondary
peak picking. Only one peak picking can be stored at the same time.
- Remove Stored Peak Picking: Ctrl + Alt + Left Click removes the stored pick picking.
