Hi Suzie,
  
In the parallel codes such as OPAL-CYCL, the prefer choose is trying to dump 
most of data into h5 file and  as less as data in ASCII file as possible.

For your purpose, there is a easy way to get the data.  
You can load the h5 file into H5root and display what you want,  then save 
this displayed figure in *.cxx format by select "File->Print" and set the 
item "Files of type" to "C++ macro".
Then you can get the data for in this code which give you the data for all 
particles on the line "graph->SetPoint(...,...,...)".


Cheers,

Jianjun Yang
