  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"]]
--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/]]
--
-- The file content can be browsed by double clicking on the file.
--
--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  :
--
--{{code language="none"}}> ln -sn beamtime path linkname
--e.g.
--> ln -sn /asap3/flash/gpfs/fl23/2025/data/11024321/ ~/beamtime_11024321 {{/code}}
--Then a “beamtime_11024321” folder should appear in your home directory.
--
--
--
--Alternativaly you can also use a conventional HDF viewer:
