Provides tools to move between adult brain EM and light level data, emphasising the interaction between the CATMAID web application and the R Neuroanatomy Toolbox package. See also, from which this package borrows a name and which was used to define the landmark data sets that provide a bridge between the FAFB EM brain and light level template.

Quick Start

For the impatient ...

# install
if (!require("devtools")) install.packages("devtools") 

# use

# run examples 

# get overview help for package 

# help for functions/data 


Currently there isn't a released version on CRAN.

Development version

You can use the devtools package to install the development version:

if (!require("devtools")) install.packages("devtools")

# to transform skeletons to template brains other than JFRC2013, you also need
# a CMTK installation (see
# and to download some additional bridging registrations.

Note that this should also install the latest version of the necessary dependencies. To carry out nblast comparisons with neurons, you may need to install optional dependencies by installing as follows:

devtools::install_github("natverse/elmr", dependencies=TRUE)

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


elmr and its dependencies are still under fairly heavy development. You can conveniently bring the development versions up to date by doing:

devtools::update_packages("elmr", dependencies = TRUE)
