data : ndarray

Array of NMR data.

dir : {‘rs’ or ‘ls’}

Direction to shift spectra, ‘rs’ for right shifting, ‘ls’ for left shifting.

pts : float

Number of points to shift.

neg : bool

True to negative points which are shifted.

sw : bool

True to update chemical shift calibration parameters.

Returns :

ndic : dict

Dictionary of updated NMRPipe parameters.

ndata : ndarray
