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.
sub_dist_mat(
neuron_names,
scoremat = NULL,
form = c("matrix", "dist"),
maxneurons = NA
)
return An object of class matrix or dist (as determined by the form argument), corresponding to a subset of the distance matrix
character vector of neuron identifiers.
score matrix to use (see sub_score_mat
for details of
default).
the type of object to return.
set this to a sensible value to avoid loading huge (order N^2) distances directly into memory.
Note that if neuron_names
is missing then the rownames of
scoremat
will be used i.e. every neuron in scoremat
will be
used.
