The code takes as an input a time series vector of calcium observations and produces samples from the posterior distribution of the underlying spike in continuous time. The code also samples the model parameters (baseline, spike amplitude, initial calcium concentration, firing rate, noise variance) and also iteratively re-estimates the discrete time constant of the model.

For initializing the MCMC sampler, the algorithm uses the constrained deconvolution method maintained separately in https://github.com/epnev/constrained-foopsi
