The noise level is very high (>>1%).
Mostly, there are head group fragments while chain fragments are of very low abundance. 

All analytes are detected, there are no FPs reported.
Chains are not detected in 14 out of 34 possible casees, and there is one FP chain identified.
The FP chains occur if one chain is detected by an NL_Carboxy_Ethanolamine and the other
by an NL_Carboxy_Ethanolamine fragment due to combinatorial reasons.
There are no position rules defined.
