DOSY NMR question

Hi, I'm looking for help to process a DOSY NMR spectrum. I'd like to know how to transform the gradient decay plot for a given region of the spectrum into a plot showing the diffusion constants (x-axis) vs the intensity (y-axis), sort of a distribution of diffusion constants. I've read about it online, and this website Diffusion NMR suggests applying an inverse laplace transform to a gaussian fitting function for the gradient decay plot, but I'm not sure how to do this. I was hoping someone could show me the steps to obtain this plot.

 

Thank you for your time.
