Fast adjacency matrices based on flywire connectome dumps

Usage

flywire_adjacency_matrix2(
  rootids = NULL,
  inputids = NULL,
  outputids = NULL,
  sparse = TRUE,
  threshold = 0,
  version = NULL,
  Verbose = interactive()
)

Arguments

rootids: flywire root ids for the bodies to fetch all by all connectivity information.
inputids, outputids: identifiers for input and output bodies (use as an alternative to rootids)
sparse: Whether to return a sparse matrix (default FALSE)
threshold: For flywire_partner_summary only return partners with greater than this number of connections to the query neuron(s) (default of 0 returns all connections)
version: Optional CAVE version. The default value of NULL uses the latest data dump available unless options(fafbseg.flywire_connectome_data_version) has been set (which you can conveniently do using flywire_connectome_data_version()). The special version of "783.2" will use the 2025 (Princeton) synapse data release.
Verbose: Logical indication whether to print status messages during the query (default T when interactive, F otherwise).

Value

A sparse matrix (Matrix::dgCMatrix) or regular matrix.

Examples

if (FALSE) { # \dontrun{
dm2pnkc=flywire_adjacency_matrix2(inputids="DM2_lPN_R", outputids="class:Kenyon_Cell_R")
} # }
