Singularity

Neurodesk Singularity Containers

Our docker containers are converted to singularity containers and stored on Object storage.

Download Singularity Containers

First get an overview of which containers are available as Singularity containers: https://github.com/NeuroDesk/neurocommand/blob/main/cvmfs/log.txt

curl -s https://raw.githubusercontent.com/NeuroDesk/neurocommand/main/cvmfs/log.txt

assign the container name to a variable:

export container=itksnap_3.8.0_20201208

Then download the containers. One way is to use CURL:

curl -X GET https://neurocontainers.neurodesk.org/$container.simg -O

Singularity Containers and GPUs

Some of our containers contain GPU-accelerated applications. Here is an example that tests the GPU accelerated program eddy in FSL:

curl -X GET https://neurocontainers.neurodesk.org/fsl_6.0.5.1_20221016.simg -O
git clone https://github.com/neurolabusc/gpu_test.git
singularity shell --nv fsl_6.0.5.1_20221016.simg
cd gpu_test/etest/
bash runme_gpu.sh

Transparent Singularity

The singularity containers can be also be used in combination with our Transparent Singularity Tool, which wraps the executables inside a container to make them easily available for pipelines. More information can be found here:

one example to do this is:

curl -s https://raw.githubusercontent.com/NeuroDesk/neurocommand/main/cvmfs/log.txt
export container=itksnap_3.8.0_20201208
git clone https://github.com/NeuroDesk/transparent-singularity ${container}
cd ${container}
./run_transparent_singularity.sh ${container}
