This function finds unique m/zs between two datasets.
1 | find.Unique.mzs(dataA, dataB, mz.thresh = 10, time.thresh = NA, alignment.tool)
|
dataA |
apLCMS or XCMS feature table for dataset A |
dataB |
apLCMS or XCMS feature table for dataset B |
mz.thresh |
Maximum m/z difference (+/-) ppm |
time.thresh |
Maximum retention time difference (+/-) seconds |
alignment.tool |
Name of the feature alignment tool eg: "apLCMS" or "XCMS" or "NA" Use "NA" if the input matrix includes only m/z or both m/z and retnetion time values. |
The find.Unique.mzs function operates on two sets of feature lists with m/z for each feature, denoted by L1 and L2, and iterates over all m/z values in L1 to find those that are within a user defined m/z (ppm) threshold in L2.
A list is returned:
uniqueA |
Unique m/zs in dataA |
uniqueB |
Unique m/zs in dataB |
