Common processing operations

Operation	Description
AUTOPHASE	Automatic phasing of current vector
BCPOLY	Baseline correction with polynomial
BCWHIT	Baseline correction with smoothed line
CSHIFT	Circular shift
DC	Baseline correction by linear offset
EXPD	Apodization with exponential decay
EXTRACT	Extract a range of the spectrum (for example the left half of an amide detected spectrum)
FDSS	Frequency domain solvent suppression
FT	Fourier transform
GM	Apodization with Lorentz to Gauss transform
HFT	Hilbert tranform to recover imaginary components of real valued spectrum
IST	Iterative soft thresholding of a 1D vector (used for 2D datasets)
ISTMATRIX	Iterative soft thresholding of an nD matrix (used for 3D and higher datasets)
LP	Extend the vector with linear prediction
LPR	Replace starting points with linear prediction
MAG	Magnitude calculation
PHASE	Adjust the phase of the spectrum
POWER	Power calculation
REGIONS	Specify regions of the vector. Typically used prior to baseline correction.
REVERSE	Reverse the spectrum
SB	Apodization with a sine or cosine window
SCRIPT	Execute a Python script. The current vector is accessible as a Python object named “vec”
TDCOMB	Form linear combinations of time domain signal using specified coefficients
TDSS	Time domain solvent suppression
ZF	Zero fill
