reproducibleANTsExample

Demonstrate how to create reproducible registration results with ANTs.

primarily, make sure you set:

export ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS=1
export ANTS_RANDOM_SEED=1

in your environment. this will work for ANTs, ANTsR or ANTsPy. make sure these are instantiated before you call R or python.

in R, these will be over-ridden but whatever is set in .Renviron.

Currently, the mutual information metric is the "most" stochastic.

This is intrinsic to the nature of the metric.

to run:

export ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS=1
export ANTS_RANDOM_SEED=1
cd src
Rscript reproducible.R
python3 reproducible.py
bash reproducible.sh
