(a) Flowchart of the process for parameterizing non-bonded interactions associated with PEI and PEI-CA. (b) An example of reparametrizing the interaction between a Qd bead in PEI and a Q0 bead in DPPC. The red dashed line represents the updated cross interaction while the black lines show the standard Martini interactions that remain unchanged.
