dataset_summary: ML Application Curated Data from The Structural Antibody Database (SAbDab)
pretty_name: The Curated SAbDab
dataset_description: >-
This dataset contains curated data from the SAbDab as of Mar 4, 2026. The
SAbDab is a database of antibody structures including experimental details,
antibody nomenclature, affinity data and sequence annotations. Additional
datasets include a ‘in_nr_set’ that was assembled by querying SAbDab with Max.
sequence identity 90% and ‘curated_quality_dataset’ that was assembled by
querying SAbDab with Max. sequence identity 90%, bound structures, resolution
below 4.0 Å. We also performed multivariate stratification on "antigen_type",
"heavy_species", "method", "scfv", "engineered", "light_ctype", "in_nr_set",
"curated_quality_dataset" to achieve an 80/10/10 train/test/validation split

ML Application Curated SAbDab
Quickstart Usage
Install HuggingFace Datasets package
Each subset can be loaded into python using the Huggingface datasets library.
First, from the command line install the datasets library
$ pip install datasets
Optionally set the cache directory, e.g.
$ HF_HOME=${HOME}/.cache/huggingface/
$ export HF_HOME
then, from within python load the datasets library
>>> import datasets
Load model datasets
To load structures from the entire SAbDab dataset, use datasets.load_dataset(...):
>>> SAbDab= datasets.load_dataset("RosettaCommons/SAbDab")
