1. A computer-implemented method for designing a biological model comprising the steps of: providing (1) a set of biological models, each biological model comprising a plurality of elements and interactions between elements; providing (2) groups of elements identified as identical, each element having an associated biological model; moving (3) an element from a first group to a second group in order to correct the grouping of the elements; updating (4) both groups; and creating (5) a combined model by combining the set of biological models according to the updated groups.
