trace_check_err¶

biophysics_fitting.ephys.trace_check_err(t, v, stim_onset=None, stim_duration=None, punish=250)¶

Returns a basic trace error that penalizes traces with low variance. Useful for an evolutionary algorithm, when the voltage trace is not spiking yet, and spike-related error functions cannot be applied yet. This tells the algorithm to reward variance in a non-spiking voltage trace – at least something is happening.

Parameters:¶

• t (array) – Time array.

• v (array) – Voltage array.

• stim_onset (float) – Time of stimulus onset.

• stim_duration (float) – Duration of stimulus.

• punish (float) – Baseline penalty for low variance. Default: 250 mV^2.
