Hello everyone,

I want to perform docking on a protein that has beryllium fluoride BeF3 as co-crystalized ligand connected to mg as cofactor. In schrodinger preperation wizard when i create zero-order metal bonds all beryllium and fluoride bonds break and further on in minmization process an error appears " restrained minmization procee failed". How can i keep the geometry and beryllium fluoride bonds during preparation? And why that error appears knowing that when i change the Be with zn atom or mg that error disappears!
