natverse Build Status Docs

Plot and analyse neurons skeletonised from image data released by FlyCircuit.

Installation

Currently there isn’t a released version on CRAN, but you can use the devtools package to install the development version:

# if necessary
if(!requireNamespace('devtools')) install.packages("devtools")
devtools::install_github("natverse/flycircuit", dependencies=TRUE)

Note: Windows users need Rtools and devtools to install this way.

Getting Started

Take a look at the package vignette (also available in fullly processed format through R’s help system).

Getting the data

We have pre-packaged a complete registered/skeletonised version of 16129 neurons from the flycircuit dataset. We are also distributing the all by all NBLAST scores for these neurons. Further details are available at https://gist.github.com/jefferis/bbaf5d53353b3944c090.

You can get the data like so:

devtools::source_gist("bbaf5d53353b3944c090")

You can also read individual skeletons hosted on the FlyCircuit website:

You could read all skeletons like so:
