Installation for Linux¶
Warning
If you use Windows Subsystem for Linux (WSL), please refer to the Windows installation section.
Requirements¶
Supported Operating Systems¶
Debian >=9
Ubuntu >= 16.04
Fedora >= 19
RedHat/CentOS >= 7
Gnu Compiler Collection (gcc)¶
You need to have gcc installed. We recommend installing it via your package manager.
For example on Debian/Ubuntu:
apt install gcc
On CentOS/RedHat:
yum -y install gcc
Installation Options¶
Option 1: Install from Package (recommended)¶
The simplest way to install SCT is to do it via a stable release. First, navigate to the latest release, then download the install script for SCT (install_sct-<version>_linux.sh). Major changes to each release are listed in the Changelog.
Once you have downloaded SCT, open a new Terminal in the location of the downloaded script, then launch the installer using the bash command. For example, if the script was downloaded to Downloads/, then you would run:
cd ~/Downloads
bash install_sct-<version>_linux.sh
Option 2: Install from GitHub (development)¶
If you wish to benefit from the cutting-edge version of SCT, or if you wish to contribute to the code, we recommend you download the GitHub version.
Retrieve the SCT code
Clone the repository and hop inside:
git clone https://github.com/spinalcordtoolbox/spinalcordtoolbox cd spinalcordtoolbox
(Optional) Checkout the revision of interest, if different from master:
git checkout ${revision_of_interest}
Run the installer and follow the instructions
./install_sct
Option 3: Install with pip (experimental)¶
SCT can be installed using pip, with some caveats:
The installation is done in-place, so the folder containing SCT must be kept around
In order to ensure coexistence with other packages, the dependency specifications are loosened, and it is possible that your package combination has not been tested with SCT.
So in case of problems, try again with the reference installation, and report a bug indicating the dependency versions retrieved using sct_check_dependencies.
Procedure:
Retrieve the SCT code to a safe place
Clone the repository and hop inside:
git clone https://github.com/spinalcordtoolbox/spinalcordtoolbox cd spinalcordtoolbox
Checkout the revision of interest, if different from master:
git checkout ${revision_of_interest}
If numpy is not already on the system, install it, either using your distribution package manager or pip.
Install sct using pip
If running in a virtualenv:
pip install -e .
else:
pip install --user -e .
Option 4: Install with Docker¶
Docker is a portable (Linux, macOS, Windows) container platform.
In the context of SCT, it can be used:
To run SCT on Windows, until SCT can run natively there
For development testing of SCT, faster than running a full-fledged virtual machine

Basic Installation (No GUI)¶
First, install Docker. Then, follow the examples below to create an OS-specific SCT installation.
Docker Image: Ubuntu¶
# Start from the Terminal
docker pull ubuntu:16.04
# Launch interactive mode (command-line inside container)
docker run -it ubuntu
# Now, inside Docker container, install dependencies
apt-get update
apt install -y git curl bzip2 libglib2.0-0 gcc
# Note for above: libglib2.0-0 is required by PyQt
# Install SCT
git clone https://github.com/spinalcordtoolbox/spinalcordtoolbox.git sct
cd sct
./install_sct -y
export PATH="/sct/bin:${PATH}"
# Test SCT
sct_testing
# save the state of the container. Open a new Terminal and run:
docker ps -a # list all containers
docker commit <CONTAINER_ID> <YOUR_NAME>/ubuntu:ubuntu16.04
Docker Image: CentOS7¶
# Start from the Terminal
docker pull centos:centos7
# Launch interactive mode (command-line inside container)
docker run -it centos:centos7
# Now, inside Docker container, install dependencies
yum install -y which gcc git curl
# Install SCT
git clone https://github.com/spinalcordtoolbox/spinalcordtoolbox.git sct
cd sct
./install_sct -y
export PATH="/sct/bin:${PATH}"
# Test SCT
sct_testing
# save the state of the container. Open a new Terminal and run:
docker ps -a # list all containers
docker commit <CONTAINER_ID> <YOUR_NAME>/centos:centos7
Enable GUI Scripts (Optional)¶
In order to run scripts with GUI you need to allow X11 redirection. First, save your Docker image:
Open another Terminal
List current docker images
docker ps -a
Save container as new image
docker commit <CONTAINER_ID> <YOUR_NAME>/<DISTROS>:<VERSION>
Create an X11 server for handling display:
Install XQuartz X11 server.
Check ‘Allow connections from network clientsoption inXQuartz` settings.
Quit and restart XQuartz.
In XQuartz window xhost + 127.0.0.1
In your other Terminal window, run:
docker run -ti --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix <CONTAINER_ID>
Option 5: Hard-core Installation-less SCT usage¶
This is completely unsupported.
Procedure:
Retrieve the SCT code
Install dependencies
Example for Ubuntu 18.04:
# The less obscure ones may be packaged in the distribution sudo apt install python3-{numpy,scipy,nibabel,matplotlib,h5py,mpi4py,keras,tqdm,sympy,requests,sklearn,skimage} # The more obscure ones would be on pip sudo apt install libmpich-dev pip3 install --user distribute2mpi nipy dipy
Example for Debian 8 Jessie:
# The less obscure ones may be packaged in the distribution sudo apt install python3-{numpy,scipy,matplotlib,h5py,mpi4py,requests} # The more obscure ones would be on pip sudo apt install libmpich-dev pip3 install --user distribute2mpi sympy tqdm Keras nibabel nipy dipy scikit-image sklearn
Prepare the runtime environment
# Create launcher-less scripts mkdir -p bin find scripts/ -executable | while read file; do ln -sf "../${file}" "bin/$(basename ${file//.py/})"; done PATH+=":$PWD/bin" # Download binary programs mkdir bins pushd bins sct_download_data -d binaries_linux popd PATH+=":$PWD/bins" # Download models & cie mkdir data; pushd data; for x in PAM50 optic_models pmj_models deepseg_sc_models deepseg_gm_models deepseg_lesion_models c2c3_disc_models deepreg_models ; do sct_download_data -d $x; done; popd # Add path to spinalcordtoolbox to PYTHONPATH export PYTHONPATH="$PWD:$PWD/scripts"
