Thanks for the very clear reply. I learnt how to store global
variables from an earlier post to the list using call("ij.Prefs.get",
<key>, <value>) ... but perhaps a single toolset would be a simpler
approach!

Is there likely to be support for multivariate fit functions in the
near future? I would like to fit a 2D polynomial to make an image
background.

many thanks
