quick tip: add export ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS=10 to your profile to enable multi-threading! can massively speed-up registration, segmentation and some basic operations ... but be careful if you are using on a cluster.

quick tip: you can link optimized numeric libraries to your installed R version in order to greatly accelerate matrix algebra. example on OSX:

cd /Library/Frameworks/R.framework/Resources/lib
ln -sf
/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Versions/Current/libBLAS.dylib
libRblas.dylib
# then in R 
system.time({ x <- replicate(5e3, rnorm(5e3)); tcrossprod(x) })
