# Model Overview ## Description: RFdiffusion (RoseTTAFold Diffusion) is a generative model that creates novel protein structures for protein scaffolding and protein binder design tasks. This model generates entirely new protein backbones and designs proteins that can be specifically tailored to bind to target molecules.
This model is available for commercial use.
## Third-Party Community Consideration This model is not owned or developed by NVIDIA. This model has been developed and built to a third-party’s requirements for this application and use case; see link to Non-NVIDIA [GitHub Model Card](https://github.com/RosettaCommons/RFdiffusion).

## Model Version(s): RFdiffusion 2.0.0
# Training & Evaluation: ## Training Dataset: **Link:** [The Protein Data Bank](https://www.rcsb.org/)
** Data Collection Method by dataset
* Hybrid: Automatic, Human
For PDB dataset, scientists worldwide submit structural data determined by X-ray crystallography or cryo-electron microscopy (cryo-EM). This includes atomic coordinates, experimental data, and metadata about the biological macromolecules.
** Labeling Method by dataset
* Hybrid: Automatic, Human
For PDB dataset, expert biocurators review the submitted data to ensure accuracy and completeness. This involves checking the plausibility of the data and annotating it with relevant biological and chemical information.
**Properties (Quantity, Dataset Descriptions, Sensor(s)):** The training dataset used for RFdiffusion, as detailed in referenced paper, consists of protein structures sampled from the Protein Data Bank (PDB). To prepare these structures for training, a noising process is applied. This process involves simulating up to 200 steps of random modifications on the protein structures. Specifically, the modifications include perturbing the Cα coordinates with 3D Gaussian noise and applying Brownian motion to the residue orientations on the manifold of rotation matrices.
**Dataset License(s):** [CC0 1.0](https://www.rcsb.org/news/feature/611e8d97ef055f03d1f222c6).
## Evaluation Dataset: The evaluation strategy involved training the model on PDB structures (as described in Training Dataset) with added noise and then assessing its ability to denoise these structures, as well as evaluating its performance on design tasks with auxiliary conditioning information.
** Data Collection Method by dataset
* Automatic: random splits from PDB dataset.
** Labeling Method by dataset
* Automatic: random splits from PDB dataset.
The training, validation, and test splits were derived from protein assemblies in the PDB, which includes structures determined by X-ray crystallography or cryo-electron microscopy (cryoEM).
## Inference: **Engine:** PyTorch
**Test Hardware:**
* A100
* L40
* H100
