Dataset

Overview

The ownership of the SPADE Database and AMP_six_tasks dataset belongs to the iGEM team XJTLU_software 2025. If you have any questinons or suggestions, please contact us at igem@xjtlu.edu.cn(Please indicate your organization and purpose of the email).

  • The length of the peptides in the dataset is between 5 and 100.
