Hi, All,<div><br></div><div>I am trying to run QMMM for a biological system but it failed with "GEOMETRY wrong or EMAX_SPLINE too small". </div><div><br></div><div>I initially equilibrated the system with AMBER and the use amber restart file as CP2K input.</div><div>I tested one smaller system with one single ligand and water and ran QMMM without any problems.
