crossTables: Cross the original MS1 peaklist with the annotation results

In LipidMS: Lipid Annotation for LC-MS/MS DDA or DIA Data

Cross the original MS1 peaklist with the annotation results

Description

Cross the original MS1 peaklist with the annotation results.

Usage

crossTables(msobject, ppm = 5, rttol = 10, dbs)

Arguments

msobject	annotated msobject
ppm	mass tolerance in ppm.
rttol	rt tolerance to match peaks in seconds.
dbs	list of data bases required for annotation. By default, dbs contains the required data frames based on the default fragmentation rules. If these rules are modified, dbs may need to be supplied. See createLipidDB and assignDB.

Value

msobject with an annotatedPeaklist, which is a data frame with 6 columns: mz, RT, int, LipidMSid, adduct and confidence level for the annotation. When multiple IDs are proposed for the same feature, they are sorted based on the annotation level and score.
