In martin3141/spant: MR Spectroscopy Analysis Tools

Align spectra to a reference frequency using a convolution based method.

Description

Align spectra to a reference frequency using a convolution based method.

Usage

align(
  mrs_data,
  ref_freq = 4.65,
  ref_amp = 1,
  zf_factor = 2,
  lb = 2,
  max_shift = 20,
  ret_df = FALSE,
  mean_dyns = FALSE
)

Arguments

mrs_data	data to be aligned.
ref_freq	reference frequency in ppm units. More than one frequency may be specified.
ref_amp	amplitude value for the reference signal. More than one value may be specified to match the number of ref_freq signals.
zf_factor	zero filling factor to increase alignment resolution.
lb	line broadening to apply to the reference signal.
max_shift	maximum allowable shift in Hz.
ret_df	return frequency shifts in addition to aligned data (logical).
mean_dyns	align the mean spectrum and apply the same shift to each dynamic.

Value

aligned data object.
