Simulate MRS data with a similar appearance to normal brain (by default).

sim_brain_1h(
  acq_paras = def_acq_paras(),
  type = "normal_v2",
  pul_seq = seq_slaser_ideal,
  xlim = c(0.5, 4.2),
  full_output = FALSE,
  amps = NULL,
  basis_lb = NULL,
  zero_lip_mm = FALSE,
  remove_lip_mm = FALSE,
  ...
)

Arguments

acq_paras: list of acquisition parameters or an mrs_data object. See def_acq_paras.
type: type of spectrum, only "normal" is implemented currently.
pul_seq: pulse sequence function to use.
xlim: range of frequencies to simulate in ppm.
full_output: when FALSE (default) only output the simulated MRS data. When TRUE output a list containing the MRS data, basis set object and corresponding amplitudes.
amps: a vector of basis amplitudes may be specified to modify the output spectrum.
basis_lb: apply additional Gaussian line-broadening to the basis (Hz).
zero_lip_mm: zero the amplitudes of any lipid or macromolecular components based on their name starting with "MM" or "Lip".
remove_lip_mm: remove any lipid or macromolecular basis components based on their name starting with "MM" or "Lip".
...: extra parameters to pass to the pulse sequence function.

Value

see full_output option.
