Number of Branches on Last Level

As ``Number of branches on last level'' you specify the number of branches on the last level. A branch is a cluster of atom groups (units), which is structured into smaller sub-clusters on finer levels. The number of branches on the last level must be a multiple of the number of nodes. A negative number indicates, that EGO determines the number of branches on the last level automatically at run time. The utility program xpl2lis enters a negative number for the optimal number of branches, thus, no manual changes are necessary.
