Attachment of fragments to a root molecule using DOCK_SWAP. (a) For a given target AP on a root molecule an iso-table is selected at random, and the HEAD fragment is attempted to be attached. (b) If the HEAD attachment is successful, equivalent linear transformations are applied to the corresponding TAIL fragments (orientation matrix and torsion angle) to yield (c) a related group of molecules with attached iso-table TAILs.
