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

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

Arguments

mrs_data

data to be aligned.

ref_freq

reference frequency in ppm units. More than one frequency may be specified.

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).

Value

aligned data object.
