NOFI ranking
The Non-Outlier Fragment Ion ranking for enhaced DIA quantification
The NOFI ranking algorithm has been developed to assign low priority to fragment ions affected by interference. The implementation is an R script that can be customized. A future version will contain a modular version. The outline is as follows:
1) The input contains the list of SWATH fragment ion XICs from the identified and quantified peptides by software tools such as Skyline and OpenSWATH.
2) The first step in NOFI is the computation of the 4 attributes (RTd, FWHMd, IRd and IRrep) used...
