Standard:

Not detected:

01:	16:0	not detected - there is only noise present
	17:0	not detected - MS1 peak is only part of another species (m/z resolution is too low)
	18:1	not detected - +1 isotopic peak is stronger than +0

02:	16:0	removed for unknown reason
	17:0	removed for unknown reason

03:	16:0	not detected - +1 isotopic peak is overlapped by another much stronger species 
	17:0	not detected - removed by MS1 for unknown reason	



Biological:
	
There are mostly the correct ones detected. The problem is that Cer_H shows nearly the same fragments
as Cer_-OH. The only distinct fragment for one of them is NL_SPH_264 which is detectable
for Cer_-OH only. For Cer_H, the NL_2xH2O_36 is observed more often. Thus, it is defined
for Cer_H only. However, this is not always the case, therefore, some H adducts
are wrongly recognized as -OH and vice versa. In many cases, both of them (FP and correct
one) are reported in green or orange color -> automated analysis of Cer is quite
difficult for this setup.
