1.The source code of HGT-PepPI:   HGT-PepPI.zip

2. The dataset used in HGT-PepPI:  

The datasets used in this study are derived from the RCSB PDB[1], with pairs showing over 80% similarity between the training and independent test datasets removed using CD-HIT[2]. The processed datasets can be downloaded from the following links:

Train-Sequences.fasta Test167.fasta   Test251.fasta   Test1440.fasta

Tool:


HGT-PepPI utilizes ProtT5[3] for peptide and protein feature extraction. To run HGT-PepPI locally, this tool must be properly configured. Detailed instructions for installation and configuration are provided in the following links:
