In order to ensure that all the information is available when SeqPHYS or SeqPHYSLITE is run, we need to shift the SeqPHYS* later in the derivation job. This is in part because quite a few truth tools add themselves to the 'main' sequence (in order to avoid repetition of work), and those truth tools need to run before the SeqPHYS* tools that look for their output.
