Hi, I'd like to draw ionic liquid in materials studio, but I don't know how to add charge to the cation and anion, the forcefield is COMPASSIII, charges is charge using QEq, when I tried to do Geometry Opitimization task, it failed and gave an error "This model contains particles separated by less than 0.01 angstroms. Please correct this problem, and restart the calculation. Unanble to calculate energy and gradients"

Here is structure I used, it's really appreciated if anyone could share the exact steps for creating an inoic liquid structure and assigning charges to them.
