**2.4 Peptide – Protein docking of viral targets with ligands**

Hex software is a tool for calculating and representing possible docking modes of pair of protein and peptide molecules [35]. Docking screening of the target proteins and antiviral CPPs was done by HEX software version 8.0.0 and finally, the free energy of binding between receptor-peptide was obtained that is shown in **Figure 2**. The parameters used in the docking process were:
