proteinmpnn-noise020

OFoldX pipeline artifact for biomolecular design generation, using the proteinmpnn architecture.

Disclaimer

This model card was generated by the OFoldX team for an OFoldX pipeline artifact. The upstream model authors did not write this card unless explicitly stated otherwise.

OFoldX is pre-alpha research software. Check the source checkpoint, upstream release, and local validation before using the artifact for scientific or operational decisions.

Model Details

ProteinMPNN sequence-design model for protein backbones, including soluble and membrane variants.

Converted ProteinMPNN-family sequence-design checkpoint for fixed-backbone inverse folding.

• Source Release: https://github.com/dauparas/LigandMPNN
• Primary Paper: Robust deep learning-based protein sequence design using ProteinMPNN
• Upstream License: MIT for upstream ProteinMPNN and LigandMPNN code/model parameters

Usage

The artifact depends on the ofoldx library. Install it with pip:

pip install ofoldx

Pipeline Usage

Load the artifact from oteam/proteinmpnn-noise020 with the OFoldX task pipeline. Use AutoModel or AutoProcessor only when you need lower-level control:

from ofoldx.pipelines import Pipeline

pipeline = Pipeline.from_pretrained("oteam/proteinmpnn-noise020")

When a matching processor is available, load it with AutoProcessor.from_pretrained(...) and pass the processed batch to the model.

Interface

• Task: design_generation
• Artifact kind: pipeline
• Architecture: proteinmpnn
• Runtime files: manifest.json, config.json, and model.safetensors when present

Training Details

OFoldX did not train these weights. This repository contains a converted checkpoint and OFoldX runtime metadata for loading it.

Training Data

ProteinMPNN was trained for fixed-backbone protein sequence design on PDB biounits with a 2021-08-02 data snapshot. OFoldX does not redistribute the training set.

Training Procedure

Upstream ProteinMPNN trains graph-neural inverse-folding models with 48-neighbor checkpoints and multiple Gaussian backbone-noise variants. OFoldX converts released ProteinMPNN-family checkpoints into model.safetensors; it does not run ProteinMPNN training.

Evaluation

OFoldX conversion reports and contract tests validate artifact structure and checkpoint loading. Task-level scientific evaluation should be checked against the corresponding upstream model release or paper.

Limitations

• This artifact is distributed for research use.
• Inputs must match the model-specific processor and expected biomolecular representation.
• OFoldX is pre-alpha, so APIs and artifact metadata may still change before a stable release.
