Chapter 16: Events

This section allows us to change a synapse's USE value. Effect of updated USE values can be seen on a post-synaptic cell group by using appropriate reports. Define multiple EVENT sections to change USE values many times over the course of simulation.

Sample File format for USE file to be uploaded:
0 0 0 1 1 2 ...
.25 .19 .30 .25 .25 .40 ...
First row represents the post-synaptic cell index and second row specifies corresponding synapse USE value. This is similar to the format of SYNAPSE_USE report type.
Note: The header can also be copied from a USE report file (of any duration, with any intial USE values).

Description

EVENT

N/A

Indicates the start of a Event definition section.

TYPE

name

(string)

The name which is used to refer to this Event object.

USE_OVERRIDE

name	(string)
value	(real)

Name indicates the file name which has the Synapse USE values to be loaded. Value is simulation time (in seconds) at which to load the Synapse USE values from file.

CELLS

Column	(string)
Layer	(string)
CellType	(string)
Compartment	(string)

This indicates the post-synaptic cell group associated with the synapse under consideration.

SYNAPSE

name

(string)

Name of the synapse whose USE values will be replaced by values loaded from file.

END_EVENT

N/A

Indicates the end of a Event definition section.

Example

EVENT
