In spant: MR Spectroscopy Analysis Tools

Combine SVS coil data using the GLS method presented by An et al JMRI 37:1445-1450 (2013).

Description

Combine SVS coil data using the GLS method presented by An et al JMRI 37:1445-1450 (2013).

Usage

comb_coils_svs_gls(
  metab,
  ref = NULL,
  noise_pts = 256,
  noise_mrs = NULL,
  use_mean_sens = TRUE,
  use_ref_sens = FALSE,
  change_order = NULL,
  no_noise_corr = FALSE,
  bc_poly_noise = 2
)

Arguments

metab	MRS data containing metabolite data.
ref	MRS data containing reference data (optional).
noise_pts	number of points from the end of the FIDs to use for noise covariance estimation.
noise_mrs	MRS data containing noise information for each coil.
use_mean_sens	use the dynamic mean to estimate coil sensitivities.
use_ref_sens	use the reference data to estimate coil sensitivities.
change_order	change the order of the noise matrix reshaping, for testing purposes only.
no_noise_corr	assume noise is uncorrelated between coils, for testing purposes only. Defaults to FALSE.
bc_poly_noise	baseline correct the noise samples with a polynomial in the time-domain. Defaults to 2, which performs a second-order polynomial correction. Set to NULL to disable.

Value

coil combined MRS data.
