sim_brain_1h {spant}

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

Description

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

Usage

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.
