simulate_spectra: Simulate a set of spectra

In ASICS: Automatic Statistical Identification in Complex Spectra

Description

Simulate a set of spectra based on the default library with shifts

Usage

simulate_spectra(
  n.spectra,
  max.shift = 0.02,
  metab.percent = 0.5,
  metab.different = 4,
  add.noise = 0.07,
  mult.noise = 0.09
)

Arguments

n.spectra	Number of spectra to simulate.
max.shift	Maximum shift allowed for artificial deformation of pure spectra (default to 0.02).
metab.percent	Percentage of present metabolites in complex spectra (default to 0.5).
metab.different	Number of metabolites that are different between each complex spectra (default to 4).
add.noise, mult.noise	additive and multiplicative noises. By default, add.noise = 0.15 and mult.noise = 0.172

Value

A list with a data frame of simulated spectra in columns and a data frame of simulated quantifications.

Examples

spectra <- simulate_spectra(n.spectra = 10)
