This package mainly contains a plotting function ggseg
and data.frames
of different brain atlases for plotting. Plotting results of analyses on
regions or networks often involves swapping between statistical tools,
like R and Matlab, and software for brain imaging to correctly visualise
analysis results.
This package aims to make it possible to plot results directly through R.
There are currently four atlases available in the package:
dkt
- Desikan-Killany atlas (aparc).yeo7
- Yeo 2011 7 resting-state networks.yeo17
- Yeo 2011 17 resting-state network.aseg
- Automatic subcortical segmentation.
We are working on creating a detailed description in the wiki on how to
create and contribute atlases to the package. The ggseg
function
already allows you to provide it with a data.frame of a custom atlas if
you have it, but is must correspond to certain specifications to work.
Please see the wiki for information on adding atlases, or inspect the included datasets for requirements. If anything is unclear in the wiki, give us a shout out in the issues!
The package can be installed using devtools. The package includes some large datasets for the brain coordinates. Please be patient during download and install, it will take some time.
install.packages("devtools")
devtools::install_github("LCBC-UiO/ggseg", build_vignettes = TRUE)
The functions are now installed, and you may load them when you want to use them. All functions are documented in standard R fashion.
The package also has a vignette, to help you get started using it. You can access it here, or via R:
library(ggseg)
vignette("ggseg")
You can also see one of the creators blog for introductions to its use here
Don’t hesitate to ask for support using github issues, or requesting new atlases. While we would love getting help in creating new atlases, you may also request atlases through the issues, and we will try to get to it.
