efel.pyfeatures.isi.ISI_CV()[source]

Coefficient of variation of ISIs.

If the ignore_first_ISI flag is set, the first ISI will be ignored.

Return type:

ndarray | None

efel.pyfeatures.isi.ISI_log_slope()[source]

The slope of a linear fit to a loglog plot of the ISI values.

If the ignore_first_ISI flag is set, the first ISI will be ignored.

Return type:

ndarray | None

efel.pyfeatures.isi.ISI_log_slope_skip()[source]

The slope of a linear fit to a loglog plot of the ISI values, but not taking into account the first ISI values.

Uses the spike_skipf and max_spike_skip settings to determine how many ISIs to skip. .

Return type:

ndarray | None

efel.pyfeatures.isi.ISI_semilog_slope()[source]

The slope of a linear fit to a semilog plot of the ISI values.

If the ignore_first_ISI flag is set, the first ISI will be ignored.

Return type:

ndarray | None

efel.pyfeatures.isi.ISI_values()[source]

Get all ISIs, inter-spike intervals.

Return type:

ndarray | None

efel.pyfeatures.isi.ISIs()[source]

Get all ISIs, inter-spike intervals.

Return type:

ndarray | None

efel.pyfeatures.isi.burst_ISI_indices()[source]

Calculate burst ISI indices based on burst factor and ISI values.

Return type:

ndarray | None

efel.pyfeatures.isi.burst_mean_freq()[source]

Calculate the mean frequency of bursts.

Return type:

ndarray | None

efel.pyfeatures.isi.initburst_sahp()[source]

SlowAHP voltage after initial burst.

Return type:

ndarray | None

efel.pyfeatures.isi.interburst_voltage()[source]

The voltage average in between two bursts.

Return type:

ndarray | None

efel.pyfeatures.isi.inv_ISI_values()[source]

Calculate the inverse of ISI values.

Return type:

ndarray | None

efel.pyfeatures.isi.inv_fifth_ISI()[source]

Calculate the inverse of the fifth ISI.

Return type:

ndarray | None

efel.pyfeatures.isi.inv_first_ISI()[source]

Calculate the inverse of the first ISI.

Return type:

ndarray | None

efel.pyfeatures.isi.inv_fourth_ISI()[source]

Calculate the inverse of the fourth ISI.

Return type:

ndarray | None

efel.pyfeatures.isi.inv_last_ISI()[source]

Calculate the inverse of the last ISI.

Return type:

ndarray | None

efel.pyfeatures.isi.inv_second_ISI()[source]

Calculate the inverse of the second ISI.

Return type:

ndarray | None

efel.pyfeatures.isi.inv_third_ISI()[source]

Calculate the inverse of the third ISI.

Return type:

ndarray | None

efel.pyfeatures.isi.irregularity_index()[source]

Calculate the irregularity index of ISI values.

If the ignore_first_ISI flag is set, the first ISI will be ignored.

Return type:

ndarray | None

efel.pyfeatures.isi.single_burst_ratio()[source]

Calculates the single burst ratio.

The ratio is the length of the first ISI over the average of the rest. If the ignore_first_ISI flag is set, the first ISI will be ignored.

Return type:

ndarray | None

efel.pyfeatures.isi.strict_burst_number()[source]

Calculate the strict burst number.

This implementation does not assume that every spike belongs to a burst. The first spike is ignored by default. This can be changed by setting ignore_first_ISI to 0.

The burst detection can be fine-tuned by changing the setting strict_burst_factor. Default value is 2.0.

Return type:

ndarray
