# This macro demonstrates how to use secondaries nhit conditional processor
# in a RAT macro to scan through existing rootfile and output a smaller one
# syntax: rat -i input_file.root -o output_file.root conditional_Ecut.mac
#
# If there is a second event with nhits > fmaxNhits OKFALSE is returned and the
# event it not written to file.

/rat/inroot/load_default
/run/initialize

# BEGIN EVENT LOOP

# Conditionally output the event to file only if secondaryNhitsCut is true

/rat/proc/if secondaryNhitsCut         # IF
    /rat/procset nhit 100
    /rat/proclast outroot              # output the events to file
/rat/proc/endif                   # END IF

# END EVENTLOOP

/rat/inroot/read      # Read the events in from file
