Some Schiff-based metal compounds have been drawn using ChemDraw 19.0 (2D) and saved them in MDL molfile (.mol) format. They were converted to 3D using GaussView 5.0, and energy minimization was performed using Gavedit 2.5.1. However, every time I perform molecular docking in pyrx, the structures appear split or broken. What could be causing this issue, and how can it be resolved?
