burst_calc: Main Page

burst_calc: Dish states generated from a receiver node are sent here for spike and burst detection.

burst_calc is a ROS package for detecting bursts of spiking activity in a neural network. A center of activity trajectory (CAT) is calculated for each burst which is then forwarded to a dish teleop node to facilitate ARM movement. The package consists of a burst creator node, a CAT creator node, and several helper classes. This package relies on the other packages in the arm_project stack to perform properly.

Run the burst creator node by creating a BurstCreator object.
Run the CAT creator node by creating a CatCreator object.

List of nodes:

burst_creator
cat_creator

burst_creator

arm_control receives dish states from a receiver node and then detects and creates burst sequences, which are forwarded to the CAT creator node.

Usage

$ rosrun burst_calc burst_creator

topics

Subscribes to:

"dish_states_to_burst_creator": [neuro_recv/dish_state] incoming dish states

Publishes to:

"bursts_to_cat_creator": [burst_calc/burst] bursts sent to the CAT creator node
"bursts_to_dish_viz": [burst_calc/burst] bursts sent to the visualizer node
"ranges_to_cat_creator": [burst_calc/ranges] channel ranges sent to the CAT creator node
"ranges_to_dish_viz": [burst_calc/ranges] channel ranges sent to the visualizer node

parameters

Reads the following parameters from the parameter server

buffer_size
stdev_mult
burst_window

Sets the following parameters on the parameter server

N/A

services

"time_service": [time_server/time_srv] polls system time to keep the node in sync

cat_creator

cat_creator receives bursts from the burst creator node and calculates a CAT for each burst. It then publishes the CAT to the dish teleop node for ARM movement.
