DOSY peak fitting function using the original version of the Keeler model.




The function fits the Keeler model to the experimental DOSY peak and extracts the diffusion constant.

   zaxis_raw                 Z axis of the DOSY peak

   zeemanscal                inter.zeeman.scalar from the input

   sys                       sys from the input

   parameters.Ga             acquisition gradient in T/m

   parameters.pulsenpoints   number of points in the pulse shape

   parameters.Te             duration of the pulse

   parameters.Tau            duration extra dephasing gradient

   parameters.BW             bandwidth of the pulse

   parameters.Ge             encoding gradient in T/m

   parameters.chirptype      can be 'wurst' or 'smoothed'

   parameters.td             diffusion delay

   parameters.dscale         scale for diffusion coefficient

   parameters.fovmin         minimum extremity of lineshape
