Per-neuron metrics for BANC v888

Reads the compiled per-neuron metrics feather from the public GCS bucket: cable length, neuron volume, mitochondria volume, pre/post synapse counts, segregation index and a handful of other morphology / connectivity scalars (one row per neuron, keyed by banc_888_id).

Usage

banc_metrics(rootids = NULL, overwrite = FALSE)

Arguments

rootids

Optional vector of root IDs to filter to. NULL (default) returns all ~188 k rows.

overwrite

Logical. If TRUE, re-download the cached feather even if it already exists.

Value

A data frame of per-neuron metrics.

Details

Source: gs://lee-lab_brain-and-nerve-cord-fly-connectome/compiled_data/banc_888/banc_888_metrics.feather (~7.5 MB; cached under tools::R_user_dir("bancr", "cache")). No CAVE equivalent — this table is compiled offline from the segmentation graph plus the synapse table. There is consequently no source / fallback argument; the only way to refresh is to re-download with overwrite = TRUE.

Examples

if (FALSE) { # \dontrun{
m <- banc_metrics()
my_metrics <- banc_metrics(rootids = c("720575941633499884",
                                       "720575941472733451"))
} # }
