After installation of a binary kit, you start gopaw with:
UNIX> <install_path>/gopaw/<version>/bin/gopaw # UNIX here is for Linux and macOS. on Windows: DOS> <install_path>\gopaw\<version>\bin\gopaw.exe
Note that on Windows you must run from a DOS prompt (CMD.exe), it does not work from a cygwin prompt.
A distribution comes with examples to play with under the res/gopaw/examples directory. The below instructions are based on data files (for example data_B4.hdf5) found under this directory. The best is to have a local copy of this directory and work on that.
UNIX> cp -R <install_path>/gopaw/<version>/res/gopaw/examples . on Windows: DOS> xcopy /s /q /i <install_path>\gopaw\<version>\res\gopaw\examples examples
To see histograms in an HDF5 file produced by Geant4/g4tools:
UNIX> cd examples/gopaw # in this directory there is a data_B4.hdf5 file coming from the Geant4 B4 example. on Windows: DOS> cd examples\gopaw start gopaw: OS> <start gopaw>
and from the gopaw prompt:
GOPAW> h/file 1 data_B4.hdf5 | open an HDF5 file and attach it to unit 1. GOPAW> ldir | list objects in the file. directory : "default_histograms". object : "Eabs", class : "tools::histo::h1d". object : "Egap", class : "tools::histo::h1d". object : "Labs", class : "tools::histo::h1d". object : "Lgap", class : "tools::histo::h1d". directory : "default_ntuples". class : "tools::hdf5::store", name : "B4". GOPAW> cd //lun1/default_histograms GOPAW> h/plot Eabs | plot the histogram Eabs found in the default_histograms directory. GOPAW> close 1
To do a ntuple projection on an ntuple found in the data_B4.hdf5 file:
GOPAW> h/file 1 data_B4.hdf5 GOPAW> /f/units +----+------------------+-----------+ | Lu | File name | File type | +----+------------------+-----------+ | 1 | data_B4.hdf5 | HDF5_FILE | +----+------------------+-----------+ GOPAW> ldir ... GOPAW> cd //lun1/default_ntuples GOPAW> n/print B4 ******************************************************** * NTUPLE NAME= B4 ENTRIES= 1000 TITLE= ******************************************************** * Var numb * Name * Lower * Upper * ******************************************************** * 1 * Eabs * 1.80103 * 32.4403 * * 2 * Egap * 0 * 16.2602 * * 3 * Labs * 7.99212 * 171.515 * * 4 * Lgap * 0 * 82.1058 * ******************************************************** GOPAW> n/plot rg_rbw.rgauss GOPAW> zone 2 2 GOPAW> exec root_def | CERN-ROOT style.

GOPAW> close 1 GOPAW> quit Exiting from gopaw.
You can have a look at the B4.kumac file:
