Precomputed attribution scores can be downloaded from Zenodo: https://zenodo.org/communities/signature/

To generate attribution scores on new data, helper files can be downloaded from Zenodo: https://zenodo.org/records/17903196

SIGnature currently supports calculating attributions using the following models:

1. SCimilarity: pretrained weights included in helper files, but can also be downloaded here: https://zenodo.org/records/15729925

2. scFoundation: pretrained weights can be downloaded here: https://huggingface.co/genbio-ai/scFoundation/tree/main

3. scVI: pretrained weights for scVI models trained on CZI Census data can be downloaded here: https://cellxgene.cziscience.com/census-models

4. SSL-scTab: pretrained weights for self-supervised learning models trained on scTab data can be downloaded here: https://huggingface.co/TillR/sc_pretrained/tree/main
