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!

Installation

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.

User documentation (ClinicaDL)

Prepare your metadata

• clinicadl tsvtool - Handle TSV files for metadata processing and data splits

Prepare your imaging data

• clinicadl quality-check - Quality control of preprocessed data: use a pretrained network [Fonov et al., 2018] to classify adequately registered images.
• clinicadl extract - Prepare input data for deep learning with PyTorch

Hyperparameter exploration

• clinicadl random-search - Explore hyperparameter space by training random models

Train deep learning networks

• clinicadl train [classification|reconstruction|regression] - Train with your data and create a model
• clinicadl train from_json - Reproduce an experiment from a JSON file
• clinicadl train resume Resume a prematurely stopped job

Inference using pretrained models

• clinicadl predict - Predict one image or a list of images with your previously trained network

Network output serialization

• clinicadl save-tensors - Write series of input / output tensors for custom analyses

Interpretation with gradient maps

• clinicadl interpret- Interpret trained CNNs on data groups

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).
