10 10  HDF5 is a data format maintained by the HDF group. For detailed general information see [[here>>url:https://portal.hdfgroup.org/display/support||shape="rect"]]

12 -The easiest way to look at the HDF5 files from your beamtime is to use the Jupyter notebook interface to Maxwell:  [[https:~~/~~/max-jhub.desy.de/>>https://max-jhub.desy.de/]]
13 -
14 - The file content can be browsed by double clicking on the file.
15 -
16 -Typically the Jupyter notebook starts at your home directory and you have to create a (soft) link to your beamtime folder: open a terminal window (File->New-> Terminal) and create the link via :
17 -
18 -{{code language="none"}}> ln -sn beamtime path linkname
19 -e.g.
20 -> ln -sn /asap3/flash/gpfs/fl23/2025/data/11024321/ ~/beamtime_11024321 {{/code}}
21 -Then a “beamtime_11024321” folder should appear in your home directory.

895 895  If Opis is running typically on the the averaged data is saved. For several experiments it may make sense to save the information for each single bunch. This is up to now done by saving the complete ADC trace of the TOF setup. This is a huge amount of data and needs processing. This has to be performed after the beamtime in close contact to [[Markus Braune>>mailto:markus.braune@desy.de||shape="rect"]] ( responsible for [[OPIS>>url:http://photon-science.desy.de/facilities/flash/photon_diagnostics/opis_spectrometer/index_eng.html||shape="rect"]])
