The methods return matrices of lower (column
low) and upper
high) isolation window offsets. Matrices are returned
as a list of length equal to the number of input files (provided as
file names of raw mass spectrometry data objects, see below). By
default (i.e when
unique. = TRUE ), only unique offsets are
returned, as they are expected to identical for all spectra per
acquisition. If this is not the case, a message is displayed.
signature(object = "character", unique. = "logical", simplify = "logical")
Returns the isolation window for the
object. By default, only unique isolation windows
are returned per file (
unique = TRUE); if set to
matrix with as many rows as there are MS2
spectra. If only one file passed an input and
TRUE (default), the resulting
length 1 is simplified to a
signature(object = "mzRpwiz", unique. = "logical", simplify = "logical")
As above for
Laurent Gatto <firstname.lastname@example.org> based on the functionality from the
library("msdata") f <- msdata::proteomics(full.names = TRUE, pattern = "TMT_Erwinia_1uLSike_Top10HCD_isol2_45stepped_60min_01.mzML.gz") isolationWindow(f) rw <- openMSfile(f) isolationWindow(rw) str(isolationWindow(rw, unique = FALSE))
