Cell Cycle and PI

A probably stupid question for the cell-cycle gurus:

When doing cell cycle analysis (PI stained cells) here and then I have a
sample which for no apparent reason shifts in staining intensity when
compared to the others. How do you adjust for this if you do not use such a
program as Modfit to calculate the percentages of the different stages? Do
you correct the PMT voltage during aquisition in order to get the G1 peaks
at the same positon or do you change the position of the markers at
analysis (Or do you throw away the data of those samples)? If you change
the markers, do you do do this just by eye or do you use a certain
algorithm to do this? Is somebody including references as RBC nuclei?

Any answers appreciated


Greetings

Claudio
