In Coayala/MetaboTandem: Analysis and Visualization of LC-MS/MS Data

Test Peak Picking

Description

Tests peak picking parameters on a subset of the data.

Usage

test_peak_picking(
  data,
  mz_range,
  rt_range,
  p_width,
  snt,
  noise,
  prefilter = c(1, 100),
  cores = 1
)

Arguments

data	An MSnExp object in centroid mode.
snt	Minimum signal-to-noise threshold allowed
noise	Noise threshold
prefilter	Prefilter step cutoff (c(k, I)). Mass will be retained if they contain at least k peaks with intensity >= I
...	Parameters to pass to the selected method
mz.range	mz range (numeric(2)) to test peak picking parameters.
rt.range	rt range (numeric(2)) to test peak picking parameters.
p.width	Minium and maximum allowed peak width

Details

Test peak picking Function to test peak picking parameters on a data subset

Value

Modified MSnExp-class object with tested peak picking parameters.
