Hi Fred you can display the content of any hdf file with h5dump or h5ls (using the hdf5 utilities)

See the manpage or

For the other stuff Chuan has to answer.

Hi Chuan,
Something is strange with the last column of the  partstatistic.dat file
#Time/ns     tot_impac      tot_sey    TotalCharge      PartNum

You write the PartNum is the number of particles at the end of the simulation. In my case I start with a few 1e4 and endup with 4e6 particles.
When using H5root, it has a filed called Entries wich is an integer.
This field changes at every step looked at, but it never shows the same number as the PartNum, the last step it shows 79000 particles, not 4e6.
So at the end what is the difference.
How many particles do I really have  at the end of my simulation ?

I am trying to load in matlab the h5 file which is not standard, hence I have no clue about what is in the .h5 file
and writing:  h5disp('ctf3-injector-darkcurrent-1.h5')
displays a very very long list of stuff which is in !
is there any way to display only the variables and their size ? and how many step numbers are in the file.

Please note that I did not re-run the simulation since you have normally fixed the PartStatistic.dat header

Hi, Frederic, The number of particles in *.oxxx file is the number of
macro particles in simulation, however the last column in .dat file
is the number of physical particles which you are interested in. And
I'll fix the header problem as soon as possible, but it will not
affect the result you get. Best regards Chuan
