If the MS is a linear ion trap and that therefore the precursor tolerance is set to +- 2 Da for OMSSA and +1 and -3 Da for X!Tandem, would "accurate mass binning" still apply? My initial thoughts are no, since those don't seem like high accuracy settings, but I'm not sure I fully understand the use of "accurate mass binning".
