neuprint_find_neurons: Find bodies within a given ROI

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

Find bodies within a given ROI

Description

Find bodies that input/output within certain ROIs (i.e. they must have synapses in these areas)

Usage

neuprint_find_neurons(
  input_ROIs,
  output_ROIs = NULL,
  dataset = NULL,
  conn = NULL,
  all_segments = FALSE,
  ...
)

neuprint_bodies_in_ROI(
  roi,
  dataset = NULL,
  all_segments = FALSE,
  conn = NULL,
  ...
)

Arguments

input_ROIs	a vector of input ROIs. Use neuprint_ROIs to see what is available.
output_ROIs	a vector of input ROIs. Use neuprint_ROIs to see what is available.
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.
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.
all_segments	if TRUE, all bodies are considered, if FALSE, only 'Neurons', i.e. bodies with a status roughly traced status.
...	methods passed to neuprint_login
roi	a single ROI. Use neuprint_ROIs to see what is available.

Value

a n x n matrix, where the rows are input neurons and the columns are their targets

Examples

# Find some neurons with inputs in the Antennal Lobe (AL) and
# outputs in the LH
pncands=neuprint_find_neurons(input_ROIs = "AL(R)", output_ROIs = "LH(R)")
head(pncands)
plot(`LH(R).pre`~`AL(R).post`, data=pncands)


lhr=neuprint_bodies_in_ROI('LH(R)')
head(lhr)
