rmBaseline: Batch Baseline Subtraction.

In PROcess: Ciphergen SELDI-TOF Processing

Description

Baseline subtraction from each raw spectrum in 'fldr'.

Usage

rmBaseline(fldr, bseoffrda = NULL, breaks = 200, qntl = 0, 
  method = "loess", bw = 0.1, 
  SpecNames = list.files(fldr, pattern = "\\.*csv\\.*"))

Arguments

fldr	a path to where the raw spectra are stored
bseoffrda	optional; name of the file (with extension .rda) where the baseline-substracted spectra, a matrix with row-names as the m/z values and column-names as the spectrum tags, will be saved to.
breaks	see bslnoff().
qntl	see bslnoff().
method	see bslnoff().
bw	see bslnoff().
SpecNames	a vector of character strings as spectrum names.

Value

A matrix whose columns correspond to baseline-subtracted spectra with row-names as the m/z values and column-names as the spectrum names.
