ClinicaDL Documentation

ClinicaDL is the deep learning extension of Clinica, an open-source Python library for neuroimaging preprocessing and analysis. This library was developed from the AD-DL project, a GitHub repository hosting the source code of a scientific publication on the deep learning classification of brain images in the context of Alzheimer's disease. This is why some functions (label definition and data set restriction) of ClinicaDL are still specific to Alzheimer's disease context. For more information on this clinical context, please refer to our tutorial.

If you are new to ClinicaDL, please consider reading the First steps section before starting your project!

Visit our hands-on tutorial web site to try ClinicaDL directly in a Google Colab instance!


See Installation section for detailed instructions.

ClinicaDL can be installed on Mac OS X and Linux machines, and possibly on Windows computers with a Linux Virtual Machine.

We assume that users installing and using ClinicaDL are comfortable using the command line.

Pretrained models

Pretrained models for CNN networks performing classification of subjects for Alzheimer disease are proposed in here in MAPS format (ready to use with ClinicaDL >= 1.0.4). Models trained with previous versions of ClinicaDL are also available. For more details concerning the parameters used to create these models please refer to the supplementary material of [Wen et al., 2020], particularly the etable 4. All the original pretrained models, produced for the aforementioned publication are also available in this Zenodo record (note that models in this format are not useful anymore with current version of ClinicaDL).



If you want to contribute but are not familiar with GitHub, please read the Contribute section. You will also find how to run the test suite to check that your modifications are ready to be integrated.
