Fast online deconvolution of calcium imaging data

Varied lag in the online estimator.
(A,B) Performance of spike inference as function of lag for various noise levels (i.e., inverse SNR) without (A) and with positive threshold smin (B). We used correlation of the inferred spike train as similarity measure and compared to ground truth as well as to the optimally recoverable activity when the lag is unlimited as in offline processing. (C) Inferred trace with positive threshold smin for increasing lag using the data depicted in Fig 4A with high noise level (σ = 0.3). The gray lines indicate the true spike times.
