Alan Kenwright's spatially encoded COSY sequence described in https://doi.org/10.1002/mrc.4727 (Figure 4).

==Syntax==

fid=psycosy(spin_system,parameters,H,R,K,G,F)

==Arguments==

parameters.sweep sweep width in Hz

parameters.npoints number of points for both dimensions

parameters.spins nuclei on which the sequence runs,
specified as {'1H'}, {'13C'}, etc.

parameters.tmix mixing time, seconds

parameters.gamp gradient amplitude, T/m

parameters.sal_ang flip angle of the saltire chirp (degrees)

parameters.sal_dur pulse width of saltire chirp (s)

parameters.sal_del chirp pulse gradient duration (s)

parameters.sal_swp sweep width of saltire chirp (Hz)

parameters.sal_npt number of points in the saltire chirp

parameters.sal_smf saltire chirp smoothing factor

H Fokker-Planck Hamiltonian, received
from the imaging context

R Fokker-Planck relaxation superoperator,
received from the imaging context

K Fokker-Planck kinetics superoperator,
received from the imaging context

G Fokker-Planck gradient superoperators,
received from the imaging context

F Fokker-Planck diffusion and flow super-
operator, received from the context

==Outputs==

fid - two-dimensional free induction decay

==Examples==
Several examples may be found in the examples/nmr_spen directory. The PSYCOSY spectrum of salsalate is reproduced below, note that one of the two dimensions is pure shift.
