GET_SPIKE

Syntax

GET_SPIKE <ch> or GET_SPIKE ALL

Description

Reads the spike statistics of one channel, or a summary of all channels. Spike detection must have been started with SPIKE ON.

Response

One channel:

SPIKE <ch> en=<0|1> count=<n> rate_1s=<Hz> rate_ring=<Hz> last_ts=<ms> last_amp=<n> ring=<n> ready=<0|1>

Field	Description
en	1 if detection is enabled on this channel.
count	Total spikes since SPIKE ON.
rate_1s	Spike rate over the last second (Hz).
rate_ring	Spike rate over a longer rolling window (Hz).
last_ts	Time of the last spike, in ms since START.
last_amp	Amplitude of the last spike (raw counts).
ring	Number of spikes in the rolling window.
ready	1 once at least one spike has been detected.

All channels, on one line:

SPIKE_ALL en=<0|1> k=<k> pol=<pol> mask=0x<hex> <ch>:<count>/<rate_1s>/<rate_ring> ...

When detection is on, only the channels of the mask are listed.

Errors

Reply	Condition
ERR GET_SPIKE bad_arg	Missing argument or channel out of range.
