Dataset Card for Contact Prediction Dataset for RAGProtein

Dataset Summary

Contact map prediction aims to determine whether two residues, $i$ and $j$, are in contact or not, based on their distance with a certain threshold ($<$8 Angstrom). This task is an important part of the early Alphafold version for structural prediction.

Dataset Structure

Data Instances

For each instance, there is a string of the protein sequences, a sequence for the contact labels. Each of the sub-labels "[2, 3]" indicates the 3rd residue are in contact with the 4th residue (start from index 0). See the Contact map prediction dataset viewer to explore more examples.
