Set initial values for PHIs

Hello, is there any possiblity to set initial values for the PHIs for each individual in the Bayesian methods? I have a rather complex system with local minimas in the ETA distribution, thus I would like to start the subjects PHIs at values derived by eye fitting or individual fitting using seperate models. Any suggestions are highly welcome Sven ________________________________ Abbott GmbH & Co.
