nat.jrcbrains

nat.jrcbrains allows bridging registrations for Drosophila brains from Janelia Research Campus to be used with the NeuroAnatomy Toolbox suite of R packages.

Installation

You can install the development version of nat.jrcbrains from GitHub using the remotes package (part of devtools):

if (!requireNamespace("remotes")) install.packages("remotes")
remotes::install_github('natverse/nat.jrcbrains')

Example

You must first download the registrations you want from

• https://www.janelia.org/open-science/jrc-2018-brain-templates

This is most easily done as follows:

library(nat.jrcbrains)
download_saalfeldlab_registrations()

To run this example you will need JRC 2018 Female - JFRC 2010, which is included as one of the downloaded bridging registrations since v0.3.1

library(nat.jrcbrains)
library(nat.templatebrains)
# sample neurons in JFRC2 space
pd2a = read.neurons("https://ars.els-cdn.com/content/image/1-s2.0-S0896627318307426-mmc5.zip")
# note use of via argument to insist on higher quality bridging registration
# to FAFB14
pd2a.fafb14=xform_brain(pd2a, sample=JFRC2, reference="FAFB14", via=c("FAFB14um"))

Registration Formats

By default nat.jrcbrains will use registrations in the Saalfeld h5 format. As an end user, support for these registrations should be installed transparently when you install nat.jrcbrains.

ANTs format registrations

If you intend to use registrations in ANTs format, then you will need to install the suggested nat.ants package. This is turn has additional dependencies that can be hard to install. See the README for https://github.com/jefferis/nat.ants for details but essentially doing

source("https://neuroconductor.org/neurocLite.R")
neuro_install("ANTsRCore")
remotes::install_github("jefferis/nat.ants")

should do the trick.
