Find a good "key" point on a neuron to associate with annotations

The chosen point sits at the major branch point of the L2 skeleton of each neuron. By default the L2 skeleton is rerooted onto the endpoint furthest from the current root so that a simplified representation with one branch point can be calculated; without this, the longest path from the root may not contain a branch point at all. If no branch point can be identified the original root point is used as a fallback.

Usage

aedes_key_point(ids, raw = TRUE, reroot = TRUE, ...)

Arguments

ids

One or more aedes root ids (or anything accepted by aedes_ids()).

raw

Whether to return points in raw (voxel) space (default) or nm.

reroot

Whether to reroot the incoming neuron onto the furthest endpoint before simplifying.

...

Additional arguments passed to pbapply::pbsapply().

Value

An N x 3 matrix of point locations (one row per input id).

Examples

if (FALSE) { # \dontrun{
aedes_key_point('648518347569414567')
} # }
