msbackadj
Correct baseline of signal with peaks
Description
adjusts the variable baseline of a raw signal with peaks by performing the following
steps.yOut
= msbackadj(X
,Intensities
)
Estimate the baseline within multiple shifted windows of width 200 separation units.
Regress the varying baseline to the window points using a spline approximation.
Adjust the baseline of the peak signals supplied by the input
Intensities
.Return the adjusted intensity values in the output matrix
yOut
.
sets additional options specified by one or more name-value pair arguments. For example,
yOut
= msbackadj(X
,Intensities
,Name,Value
)msbackadj(X,Intensities,'WindowSize',300)
sets the width of the
shifting window to 300 separation units.
