sub_dist_mat: Convert (a subset of) a raw score matrix to a distance matrix
In nat.nblast: NeuroAnatomy Toolbox ('nat') Extension for Assessing Neuron Similarity and Clustering
Description

Description
This function can convert a raw score matrix returned by nblast
into a square distance matrix or dist object. It can be used with
file-backed matrices as well as regular R matrices resident in memory.
Usage
1
2
sub_dist_mat(neuron_names, scoremat = NULL, form = c("matrix", "dist"),
maxneurons = NA)
Arguments
neuron_names
character vector of neuron identifiers.
scoremat
score matrix to use (see sub_score_mat for details of
default).
form
the type of object to return.
maxneurons
set this to a sensible value to avoid loading huge (order
N^2) distances directly into memory.
Details
Note that if neuron_names is missing then the rownames of
scoremat will be used i.e. all neuron in scoremat will be used.
Value
return An object of class matrix or dist (as determined by the form
argument), corresponding to a subset of the distance matrix

Other scoremats: nhclust
