Bayes processing in 2.6
Posted by paulbarber on 2011-11-16 11:37
A safe way to setup Bayes analysis at the moment is to get the cursors correct, and prompt loaded if you have one, using a Marquardt fit. Press "Estimate Cursors" if you can as this does some Bayes initialisation. Then go into the Bayes configuration panel. For exploring single transients it is best to untick the "Use rapid Bayesian Analysis" box to use the full numerically continuous Bayes algorithm. You can then try a Bayesian fit. I you are doing FLIM then the rapid method will speed things up when processing whole images. Then you must take care of the Tau and w0 spacing based on the parameter values you have got so far from the other methods. These must be set to conservatively contain the full probability function and 50% to 200% of a particular parameter may be sufficient. To explore this further call on the "Bayesian Probability Distribution Analysis" panel. When you click "Add Plot" (maybe need to "Clear Graph" then "Add Plot") the local area of the probability distribution will be plotted and should show a peak at the favoured parameter values, the spacing and limits set for rapid Bayes must completely contain this peak.
