[Xplor-nih] help

Hi, I am a new user of xplor. Now I want to use it to calculate the structure of G-quadruplex. But I do not know how to add the planarity constraints into the structure calculation. I wonder whether there is someone who the similar work and could share his experience. If a modified topology file is needed during the calculation, anyone could share it with me. many thanks.
