sim_resonances {spant}

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

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,
  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)
