Compilation

Compile the package with HDF5 option enabled
1. Using cmk script: ./cmk.sh -hj9 -d [path of hdf5 dir] (-d is optional and for custom installation folder)
2. Enable using cmake option -DSLS_USE_HDF5=ON and -DCMAKE_INSTALL_PREFIX=/path/to/custom/hdf/installation (optional).

Setup

Start Receiver process
Load config file
Set file format using command fformat.
```
sls_detector_put fformat hdf5
```
