# webProteinMPNN model assets

This directory contains browser-oriented ONNX conversions of the official
ProteinMPNN checkpoint families used by
https://github.com/MurrellGroup/webProteinMPNN.

## Layout

Each model directory contains:

- `manifest.json`: dimensions, atom mode, filenames, SHA-256 integrity hashes,
  upstream commit, and source checkpoint SHA-256.
- `encoder.onnx`: structure encoder with dynamic residue and neighbor axes.
- `decoder-step.onnx`: incremental autoregressive decoder.
- `decoder-full.onnx`: parallel decoder used for scoring and probabilities.
- `embedding.bin`: little-endian float32 sequence-token embedding table.

Available families and checkpoints are listed in `catalog.json`. ProteinMPNN
and solubleMPNN models consume N/CA/C/O backbone coordinates; CA models consume
CA-only coordinates. All bundles use the alphabet `ACDEFGHIKLMNPQRSTVWYX`.

The conversions were produced by `proteinmpnn-web/0.1.0` from upstream commit
`8907e6671bfbfc92303b5f79c4b5e6ce47cdef57`. They are designed for ONNX
Runtime Web 1.24.3 and can run with its WASM or WebGPU execution provider.
