# PRIDE Crosslinking Archive

<!-- Provide a quick summary of the dataset. -->

This dataset aggregates publicly available crosslinking mass spectrometry (XL-MS) datasets from the PRIDE repository.
Each dataset is curated and categorized by crosslinking reagent a link type (inter-chain vs intra-chain). For intra-chain links where the protein can be mapped to a
UniProt ID, each link is mapped onto the corresponding AlphaFold Database (AFDB) structure, and the Cα-Cα distance for the linked residue pair is reported.

The result is a standardized resource for analyzing XL-MS constraints across reagents and for benchmarking/evaluating integrative modeling pipelines.

## Quickstart Usage

### Install HuggingFace Datasets package

Each subset can be loaded into python using the Huggingface [datasets](https://huggingface.co/docs/datasets/index) 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 one of the `PRIDE_Crosslinking_Archive` datasets, use `datasets.load_dataset(...)`
