To experiment with the ICTR HDF5 Lagrangian data format first you will need to have all the HDF5 libraries and executables. 

You can get them from here: http://hdf.ncsa.uiuc.edu/HDF5/

1. Download the latest tarball file (presently: hdf5-1.6.5.tar.gz) and uncompress it on your HOME dir.
2. Change directory: "cd hdf5-1.6.5"
3. Configure: "./configure --prefix=$HOME/hdf5"
4. Build: "make check"
5. Install: "make install"
6. Add to to your PATH environment variable: "$HOME/hdf5/bin/"

Now you are ready to get an example datafile. To get one :

1. Anonymous ftp on sp.sp5.cineca.it as user cmprm001
2. "cd HDF5"
3. "get RM-2006-LIGHT-512.St0.0.h5" (notice: directory listing does not work, the example file is 100Mbytes)

At this point you may want to give a glance inside the data...:

"h5dump  RM-2006-LIGHT-512.St0.0.h5" will show the content of the HDF5

To decode in a snap the data, you may want to fetch the ICTR HDF5 myhdf5.h library for C.

To download the library myhdf5.h necessary to compile the example readout program:

http://viewcvs.cineca.it/viewvc/ictr-libs/myhdf5.h?root=ICTR

While to get the whole tar-gz with libray, example.c and Makefile :

http://viewcvs.cineca.it/viewvc/ictr-libs.tar.gz?root=ICTR&view=tar

After uncompressing it, type "make" and then run the test program "./example"
