In neuroconductor/spant: MR Spectroscopy Analysis Tools

Description

Simulate a MRS data object containing a set of simulated resonances.

Usage

sim_resonances(
  freq = 0,
  amp = 1,
  lw = 0,
  lg = 0,
  phase = 0,
  freq_ppm = TRUE,
  acq_paras = def_acq_paras(),
  fp_scale = TRUE,
  back_extrap_pts = 0
)

Arguments

freq	resonance frequency.
amp	resonance amplitude.
lw	line width in Hz.
lg	Lorentz-Gauss lineshape parameter (between 0 and 1).
phase	phase in degrees.
freq_ppm	frequencies are given in ppm units if set to TRUE, otherwise Hz are assumed.
acq_paras	list of acquisition parameters. See def_acq_paras
fp_scale	multiply the first data point by 0.5.
back_extrap_pts	number of data points to back extrapolate.

Value

MRS data object.

Examples

sim_data <- sim_resonances(freq = 2, lw = 5)
