PyTrA v.1.0

The first version of PyTrA is now released and available on the Photon Factory webpage for download.

The new version has a new interface that makes data exploration much easier. Fitting can be done of the kinetics and the spectra and Markov Chain Monte Carlo can be applied to both dimensional fits.

This allows for model checking using Bayesian methods that were not possible before. The noise of the data is also included in the MCMC fitting this allows for quantification of noise levels and to determine the signal to noise ratio accurately.

Next version will add variable projection global fitting as well as MCMC global fitting coupled with custom models. This should allow complicated models including multiple decays and complex kinetic models as well as artifacts and bleaches to be fitted using Bayesian or global methods.
