Distribution of mass shifts and non-aligned masses on the HEK293 dataset interpretation with SpecGlobX downstream to SpecOMS (FDR < 1%). a A general histogram overview shows the major peaks. b In this detailed histogram above, non-aligned major peaks around 1 Da have been removed and the mass delta scale is reduced from − 200 to 400 Da so that minor peaks can be observed. The number of mass shifts in each 1 Da wide bin is represented in orange. c In the detailed histogram below, the number of non-aligned mass shifts in each 1 Da wide bin is represented in blue
