seglengths: Calculate length of all segments in neuron

In nat: NeuroAnatomy Toolbox for Analysis of 3D Image Data

Calculate length of all segments in neuron

Description

Calculate length of all segments in neuron

Usage

seglengths(x, all = FALSE, flatten = TRUE, sumsegment = TRUE)

Arguments

x	A neuron
all	Whether to calculate lengths for all segments when there are multiple subtrees (default: FALSE)
flatten	Whether to flatten the lists of lists into a single list when all=TRUE
sumsegment	Whether to return the length of each segment (when sumsegment=TRUE, the default) or a list of vectors of lengths of each individual edge in the segment.

Details

A segment is an ubranched portion of neurite consisting of at least one vertex joined by edges.Only segments in x$SegList will be calculated unless all=TRUE. Segments containing only one point will have 0 length.

Value

A vector of lengths for each segment or when sumsegment=FALSE a list of vectors
