Return information about connectors joining sets of pre/postsynaptic skids

Description

Return information about connectors joining sets of pre/postsynaptic skids

Usage

catmaid_get_connectors_between(
  pre_skids = NULL,
  post_skids = NULL,
  get_names = FALSE,
  pid = 1,
  conn = NULL,
  raw = FALSE,
  ...
)

Arguments

pre_skids, post_skids	Skeleton ids in any form understood by catmaid_skids or NULL meaning no restriction.
get_names	Whether to fetch the neuron name for each pre- and post-synaptic skid (default FALSE).
pid	project id (default 1)
conn	the catmaid_connection object
raw	Whether to return completely unprocessed data (when TRUE) or to convert the nodes and connectors lists into processed data.frames (when FALSE, the default)
...	Additional arguments passed to the catmaid_fetch function.

Details

If either the pre_skids or post_skids arguments are not specified (taking the default NULL value) then this implies there is no restriction on the pre- (or post-) synaptic partners.

Each row is a unique set of pre_synaptic node, post_synaptic node, connector_id. A rare (and usually erroneous) scenario is if the same pre_node and post_node are present with two different connector_ids - this would create two rows.

Value

A data.frame with columns

• pre_skid

• post_skid

• connector_id

• pre_node_id

• post_node_id

• connector_x

• connector_y

• connector_z

• pre_node_x

• pre_node_y

• pre_node_z

• post_node_x

• post_node_y

• post_node_z

• pre_confidence

• pre_user

• post_confidence

• post_user

• pre_name (optional - the name of the presynaptic neuron)

• post_name (optional - the name of the postsynaptic neuron)
