 ## Dataset Description
@@ -19,6 +19,8 @@ This repository provides several enhanced versions of the **PPB-Affinity dataset
 
 This version of the dataset was prepared for the study: "*[Beyond Simple Concatenation: Fairly Assessing PLM Architectures for Multi-Chain Protein-Protein Interactions Prediction](https://arxiv.org/pdf/2505.20036)*."
 
+Code: https://github.com/Proteinea/ppiseq
+
 The primary enhancements in this repository include:
 * Various levels of data filtration and processing.
 * The addition of pre-extracted "Ligand Sequences" and "Receptor Sequences" columns, making the dataset ready for use with sequence-based models without requiring PDB file parsing. For complexes with multiple ligand or receptor chains, the sequences are comma-separated.
@@ -106,6 +108,4 @@ All configurations share a common set of columns. These include columns from the
 * **`Ligand Sequences`**: `string` - Comma-separated amino acid sequences of the ligand chain(s).
 * **`Receptor Sequences`**: `string` - Comma-separated amino acid sequences of the receptor chain(s).
 
-**Note on Sequences**: When multiple ligand or receptor chains are present in a complex, their respective amino acid sequences are concatenated with a comma (`,`) as a separator in the "Ligand Sequences" and "Receptor Sequences" fields.
