In natverse/neuprintr: R Client Utilities for Interacting with the neuPrint Connectome Analysis Service

Get the IDs and 3D locations of the pre- and post- synapses that make up a synaptic object

Description

Get synapse IDs for a given connector ID, as well as their associated body IDs and their locations in 3D space.

Usage

neuprint_connectors(
  connector_ids,
  all_segments = TRUE,
  conn = NULL,
  dataset = NULL,
  ...
)

Arguments

connector_ids	a vector of IDs (pre- or postsynapse IDs) for a synaptic connection object.
all_segments	if TRUE, all bodies are considered, if FALSE, only 'Neurons', i.e. bodies with a status roughly traced status.
conn	optional, a neuprintr connection object, which also specifies the neuPrint server. If NULL, the defaults set in your .Rprofile or .Renviron are used. See neuprint_login for details.
dataset	optional, a dataset you want to query. If NULL, the default specified by your R environ file is used or, failing that the current connection, is used. See neuprint_login for details.
...	Additional arguments passed to neuprint_fetch_custom

Value

a data frame, where each entry gives the pre-post associations for a synapse. This includes which are the pre/post synaptic bodyids (neurons/fragments) and the location of these synapses in 3D space (likely raw voxel space).

Examples

syns = neuprint_get_synapses(818983130) # note
# all given connectorIDs from this function are for presynapses
prepost.conn = neuprint_connectors(syns$connector_id, all_segments = TRUE)
head(prepost.conn) # All the synapses that connect to or from 818983130
# and their other connections to other bodies too
