Install
The quickest way to install is:
if (! 'devtools' %in% installed.packages()) install.packages('devtools')
devtools::install_github('dorianps/LESYMAP')This will install all the dependencies, including ANTsR (may take one hour on some computers). Here is the video of the installation process. If it doesn’t work, check out the more detailed installation instructions.
Docker container
If you use Docker, we have built a container with LESYMAP pre-installed (along with RStudio). We have also built scripts to start and stop the LESYMAP container easily (for Windows, Linux, Mac). See the instructions here and you should be good to go in minutes:
