## Body information

Body list: The list of all the bodies are shown in default.&#x20;

\#pre: Number of pre synapses on that body

\#post: Number of post synapses on that body

Body filter: Filter the list of the result by any words or numbers in the columns&#x20;

&#x20;(Body ID, name, #pre, #post, or status)

Goto button: Selected bodies on the list will be sent to the main proofreading window.
