The description of the elements is followed by the description of their connections to each other, i.e. the dataflow.It consists of a list of elements pairs, separated by the new line. The following format is used for a pair:
element1_name.slot1_name->element2_name.port2_name.slot2_name
This pair says that data from slot1 of element1 will be transferred to slot2 of port2 of element2.See, for example, the minimum description of a dataflow of a workflow, that aligns an input MSA and writes the result to a file in ClustalW format.
