Predict the L/R side of Aedes neurons

Returns the logical side of each requested neuron. The side can come from the manual side annotation in the FlyTable metadata (when present) or be derived from the soma's position relative to the Aedes midline via aedes_point_side.

Usage

aedes_soma_side(
  ids,
  method = c("auto", "manual", "position"),
  threshold = 0,
  mesh = aedes::aedes_neuropil_mesh,
  chunksize = 20L,
  cl = NULL,
  version = NULL,
  timestamp = NULL
)

Arguments

ids

Root IDs, a query string (see aedes_ids), or a pre-fetched metadata data.frame from aedes_meta (must contain a root_id column).

method

One of "auto" (default), "manual", "position". See Details.

threshold

Absolute X displacement (nm) below which position reports a soma as midline ("M"). Default 0. Ignored by manual.

mesh, chunksize, cl

Forwarded to aedes_soma_position.

version, timestamp

Optional CAVE materialisation selectors, forwarded to aedes_meta and aedes_soma_position.

Value

A character vector of "L", "R", "M", "U" or NA, one entry per input root id.

Details

Methods:

auto

Try manual first, then fill any remaining NAs using position.

manual

Read the side column of aedes_meta. Values are uppercased; entries outside "L", "R", "M", "U" become NA.

position

Classify each soma by its signed displacement from the Aedes midline via aedes_point_side. threshold is forwarded as-is; the default 0 means position never returns "M". "M" is reserved for bilaterally symmetric / unpaired neurons annotated as such.
