24:0 is not found in samples 1, 2 and 5  - spectra are very bad. For 34:1, there is
one time no spectrum detected, and in the remaining cases, chain assignment is
not possible. For 34:0 and 38:0, chain assignment is not possible in one case, and
for 36:2 in two cases. However, in 3 out of these 4 cases, chain assignment would
be possible if the BasePeakCutoff is reduced to 0.4%, but this was not done
due to additional FP peaks in the bioligical data.

Even though there are many different fragments, the fragment relationships
are very often contradicting (in some samples they would work well). Due to this
unreliability, no positional assignment was made. 

Compared to ms1 only quantification, fragrules kick out the FP 34:1 at a retention time of 11.82.
