nat.flybrains provides additional data and functions for use with the NeuroAnatomy Toolbox (nat). In particular nat.flybrains defines the physical properties of a number of commonly used template brains in Drosophila neuronatomy including:
along with bridging registrations between some of these template brains (see https://github.com/jefferislab/BridgingRegistrations) and functions to transform objects such as nat neurons from one space to another as simply as:
# convert neuron from IS2 space to JFRC2 space myneuron.jfrc2=xform_brain(myneuron, sample=IS2, reference=JFRC2) # flip neuron to opposite hemisphere of JFRC2 space myneuron.jfrc2.flip=mirror_brain(myneuron.jfrc2, JFRC2) # to install additional/updated registrations # (beyond those distributed as part of the R package) # Strongly recommended! download_jefferislab_registrations() # for more information JFRC2 IS2 ?xform_brain ?mirror_brain
This package is fully functional but there are presently no plans to release a version to CRAN, since there is a significant amount of data included with the package (and CRAN discourages large packages).
You can, however, download the tar ball,
R CMD INSTALL on it, or (highly recommended) use the devtools package to install straight from github:
# install devtools package if you don't already have it if (!require("devtools")) install.packages("devtools") # nb this will install the generic templatebrains package from CRAN devtools::install_github("jefferislab/nat.flybrains") # to install additional/updated registrations # (beyond those distributed as part of the R package) # Strongly recommended! nat.flybrains::download_jefferislab_registrations()
