This repository contains scripts, data and jupyter notebooks used to produce the evaluation results in the BioPhi 2021 publication:

David Prihoda, Jad Maamary, Andrew Waight, Veronica Juan, Laurence Fayadat-Dilman, Daniel Svozil & Danny A. Bitton (2022) BioPhi: A platform for antibody design, humanization, and humanness evaluation based on natural antibody repertoires and deep learning, mAbs, 14:1, DOI: https://doi.org/10.1080/19420862.2021.2020203

Data

All data files are found in data.

See more about each evaluation task in data/tasks:

• OASis: humanness evaluation using IMGT/mAb-DB
• OASis: humanness evaluation using immunogenicity data
• Sapiens: humanization evaluation using Hu-mAb 25 pairs
