between actors are controlled by the pull-down menus, which
represent the cells of the matrix. Each pull-down menu has 5 different values,
starting from the empty one, indicating no relation, up to very strong,
representing the strongest possible relation. Relations are always directed and
start at the actor listed on the left side, and end at the actor listed on the
top of the matrix.
