# PoreFM-DNA

Pretrained PoreFM model for Oxford Nanopore DNA signals.

Model version: **0.1.0**. Chemistry: **R10.4.1 (E8.2, 400 bps)**. Embedding dimension: **384**.

| File | Contents |
|---|---|
| `backbone.pt` | Backbone for embeddings and downstream tasks. |
| `pretraining.pt` | Backbone, pretraining objective heads, and EMA target encoder; optimizer and scheduler states are excluded. |

Model configuration and preprocessing are embedded in the checkpoints. Setup and usage are documented in the PoreFM code repository.

`manifest.json` records artifact identities and tensor fingerprints. `SHA256SUMS` verifies checkpoint downloads. Tensor fingerprints are independent of descriptive metadata; file hashes identify exact bytes. Documentation-only changes leave the model version unchanged.
