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,
  sum_resonances = TRUE
)

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.
sum_resonances: sum all resonances (default is TRUE), otherwise return a dynamic mrs_data object.

Value

MRS data object.

Examples

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