The Runlog Output processor can only be run on data structures input via RLR as described above. It transfers all the n-tuple and histogram banks to the HBOOK file designated in the RLO 1 file command. Each run gets written to its own sud-directory named by run number extended to 10 digits, so run 1183 is stored in 0000001183. In this way there is no confusion when processing multiple runs in a single job. Once this HBOOK has been created it can be analysed by PAW in the normal way.
