class biophysics_fitting.hay.evaluation.StepOne

Evaluate Step current one.

This class initializes all the evaluation metrics for the StepOne stimulus protocol. The empirically observed objectives are in this case:

Parameters:

  • soma_thresh (float) – The threshold for APs in the somatic voltage trace. Defaults to \(-30\ mV\).

  • stim_onset (float) – The onset of the stimulus (\(ms\)). Defaults to \(700\ ms\).

  • stim_duration (float) – The duration of the stimulus (\(ms\)). Defaults to \(2000\ ms\).

  • punish (float) – The punishment value in units of \(\sigma\). Used as a baseline if the voltage trace cannot be evaluated on a metric (e.g. if it does not contain an AP). Defaults to \(250 \sigma\).

  • punish_last_spike_after_deadline (bool) – Whether to punish if the last spike is after the deadline. Defaults to True

  • punish_minspikenum (int) – The minimum number of spikes required for this stimulus protocol. Defaults to \(5\).

  • punish_returning_to_rest_tolerance (float) – The tolerance for returning to rest (\(mV\)). Defaults to \(2 mV\).

  • definitions (dict) – The definitions for the evaluation metrics. See also: definitions.

  • name (str) – The name of the stimulus protocol. Defaults to 'StepTemplate'.

  • step_index (int) – The index of the step stimulus protocol. Defaults to \(0\). Options are: [1, 2, 3].
