spike_gui module

class opeth.spike_gui.SpikeEvalGui(sample_rate)

Bases: object

Spike evaluation plots for a given channel.

Three main areas: top part is a full timeline plot displaying the original signal with the detected spikes overlayed in different color, and the bottom part is a per-spike grid of plots displaying the detected spikes individually. On the right side parameters can be adjusted.

GUI initialization

spikeplotpool

List of plots in the grid (not used)

Type:list

spikeplotcurves

Spike waveforms in spikeplotpool used for setData

Type:list

spikeplotpositions

Marker for the detected threshold crossing

Type:list

spikerawcurves

Curves to overlay the top display with the color of specific spikes

Type:list

spikeplotpool_next

Index of current spike in the given round of plots (for color and plot window cycling)

Type:int

COLORS = ['1f78b4', 'b2df8a', '33a02c', 'fb9a99', 'e31a1c', 'fdbf6f', 'ff7f00', 'cab2d6', 'a6cee3']

MAX_PLOT_PER_SEC = 5

Continuous spike window refresh rate (if “Update only on spike” not selected)

NOF_SPIKEPLOTS = 9

Bottom spike window grid settings

NOF_SPIKEPLOTS_PER_ROW = 3

Bottom spike window grid settings

PENWIDTH = 2

Plot draw width

SPIKE_ROI_AFTER = 0.001

in seconds after peak of spike

Type:Bottom display limit

SPIKE_ROI_BEFORE = 0.0003

in seconds before peak of spike

Type:Bottom display limit

close()

Called when main window is closed.

earliest_plot = None

timestamp until new plot is created to limit update frequency

plot(data_ts, data, spike_ts, spike_pos, threshold_levels)

Plot a set of data and corresponding spikes on the selected channel.

Parameters:

• data_ts – timestamps
• data – data to plot - only the selected channel will be plotted
• spike_ts – timestamps where spikes were detected by colldata.DataProc.spikedetect().
• spike_pos – spike positions as detected by colldata.DataProc.spikedetect().
• threshold_levels – per channel threshold level for plotting
