Heavy-ion collisions at intermediate energies are studied by the isospin-dependent quantum molecular dynamics model in the company of the GEMINI model. The isospin-dependent quantum molecular dynamics model is applied to describe the violent stage of the collisions, while the GEMINI model is applied to simulate the decays of the prefragments. The present study mainly focuses on the odd-even effect in the yields of the final fragments. We find that the odd-even effect appears in the deexcitation process of the excited prefragments, and is affected by the excitation energies and the isotope distributions of the prefragments. Both the projectile-isospin-dependent odd-even effect in the region of -4{<=}T{sub Z}{<=}1 and the role of the symmetry energy on the odd-even effect are studied. We find that the odd-even effect depends sensitively on the symmetry energy.
