In spant: MR Spectroscopy Analysis Tools

Corrected zero order phase and chemical shift offset in 1H MRS data from the brain.

Description

Corrected zero order phase and chemical shift offset in 1H MRS data from the brain.

Usage

phase_ref_1h_brain(
  mrs_data,
  mean_ref = FALSE,
  ret_corr_only = TRUE,
  xlim = c(4, 1.9),
  p_deg = 3,
  sp_N = 2,
  basis_type = "poly"
)

Arguments

mrs_data	MRS data to be corrected.
mean_ref	apply the phase and offset of the mean spectrum to all others. Default is FALSE.
ret_corr_only	return the corrected data only.
xlim	frequency range in ppm to consider.
p_deg	polynomial baseline order.
sp_N	number of spline functions, note the true number will be sp_N + sp_deg.
basis_type	may be one of "poly" or "spline".

Value

corrected MRS data.
