Hello Amber Users and Developers,
I am attempting to simulate an unbinding of a porphyrin (charge +4) from a G-quadraplex structure. Since I am fairly new to this approach I followed the tutorial for ASMD and obtained a PMF curve at 10 A/ns pulling speed. But I realized that my ligand is highly positively charged and the PMF would obviously keep rising due to Coulombic forces. I would highly appreciate your experienced insight on handling such situations. My inputs were the same as was suggested in the Amber Tutorial 26. I have amended my resulting PMF curve as well.
Thank you
Senal
