1. create a working directory /work/
2. Go to work/
3. Create softlinks to field maps, pulse shapes, layout files, etc. by typing
   /home/dlr/development9_linux/g-2/soflink_lnx
4. Input parameters are enumerated in a file called 'input.dat'
   copy /home/dlr/development9_linux/g-2/mytest/fiber/chromaticity/input.dat .
5. Ring layout and lattice  parameters are defined in the lattice file
   copy /home/dlr/development9_linux/g-2/mytest/fiber/chromaticity/bmad_equad_grid. .
6. Quad alignment and voltages are defined in quad_input.dat and quad_plate_misalign.bmad
   copy /home/dlr/development9_linux/g-2/mytest/fiber/chromaticity/quad_input.dat .
   copy /home/dlr/development9_linux/g-2/mytest/fiber/chromaticity/quad_plate_misalign.bmad .

Now you have all of the files that you will need to run the progam with the command

      /home/dlr/development9_linux/production_bin/g2_tracking

With each execution of the program, a subdirectory is created with name = <yearmmdd_hhmmss>
and the output generated by the program is written to that subdirectory (including the input files)

The fiber harp - fiber hit data is written to 'fiber_hits.dat'
To combine the fiber hits data from multiple runs create the file
 'flist.dat'
and run the program 
  /home/dlr/development9_linux/production/bin/analyze_fibers_harp
  
Here is an example 'flist.dat' file. It is a namelist file. It lists all of the fiber_hits.dat files to be combined.
