Noise cutoff (not currently implemented)

Calculation

Metric describing whether an amplitude distribution is cut off, similar to _amp_cutoff amplitude cutoff but without a Gaussian assumption. A histogram of amplitudes is created and quantifies the distance between the low tail, mean number of spikes and high tail in terms of standard deviations.

A SpikeInterface implementation is not yet available.

Expectation and use

Noise cutoff attempts to describe whether an amplitude distribution is cut off. The metric is loosely based on [Hill]’s amplitude cutoff, but is here adapted (originally by [IBL]) to avoid making the Gaussianity assumption on spike distributions. Noise cutoff provides an estimate of false negative rate, so a lower value indicates fewer missed spikes (a more complete unit).

Literature

Metric introduced by [IBL] (adapted from [Hill]’s amplitude cutoff metric).
