3.4.4 dump

Used in conjunction with option,fifo=<filename> to output the bunch distribution at a given point. If the specified output file is a FIFO, the distribution can be modified by an external program before being piped back in to continue tracking. This is useful for including multi-particle effects such as wakefields at given points in the lattice.

     dump,range=dumpMarker1
     option,fifo="/tmp/temp.dat"

Output is in the standard Guineapig format, with a header line stating the number of particles to be output. The file to be read back should be in the same format as this.
