Sabatier and the group of the Laboratoire de Physique Mathematique of Montpellier University for warm hospitality while this work was in progress. Partial financial support from the Comision Asesora de Investigacion Cientifica y Tecnica, Spain is also acknowledged.The effect of the radiation modes on soliton motion in nonlinear lattices is investigated. A method based on the inverse scattering transform is developed, which enables us to characterize the position shifts of solitons due to their interaction with the radiation component.
