8-spot realtime kinetics

The following notebook analyzes the raw multispot realtime kinetics smFRET data for the different measurement replicates. Burst search results and FRET efficiencies fits are computed on a moving time window:

After this preprocessing the data is summarized and plotted in:

1-spot bubble-bubble kinetics - Run-All

Similarly, single-spot μs-ALEX smFRET on the same sample is analyzed in:

And summarized in:

Comparison of multispot vs single-spot kinetics

Simulations

Simulations have been performed to study the fitting accuracy of each parameter when using the simple-exponential and integrated-exponential models for a range of conditions. We test noise levels typical for both multispot and single-spot measurements. For each noise level we performed the model comparison allowing $t_0$ (the origin of the transient) to vary or not.

All these simulations are performed in:

Finally, the notebook:

studies how the variance of a Gaussian random process scales with the size of a moving integration window and the effect of overlapping or non-overlapping windows.
