26 == General information about HDF5 ==
27
28 HDF5 is a data format maintained by the HDF group. For detailed general information see [[here~[~[image:url:http://hasfweb.desy.de/pub/TWiki/TWikiDocGraphics/external-link.gif~|~|width="13" height="12"~]~]>>url:https://www.hdfgroup.org/HDF5/||shape="rect"]]

38 == FLASH HDF5 structure ==
39
40 The photon diagnostic, electron diagnostic and beamline information as well as the information about the pump-probe laser and the infrastructure offered for users (GHz/MHz ADCs) can be included in one HDF5 file which is organised according to train IDs. The general structure is:
41
42 * Electron Diagnostic
43 * Photon Diagnostics
44 * Beamlines
45 * Experiment
46 * Timing

1045 === HDF5 structure revisions ===
1046
1047 Starting with Beamblock 4, August 2018, the hierarchy of the HDF group names have been adapted to reflect the new situation at FLASH. FLASH2 is operating for users quite some time now. Therefore, both accelerators appear equally in their respective HDF groups, namely "/FL1" and "/FL2". The root group of proper, by run organised HDF files have an attribute called "version". This version attribute has changed from "0.2.x" to "0.3.x". The changes in detail:
1048
1049 \\
1050
1051 * All FLASH1 related HDF groups moved to group "/FL1", i.e. a new prefix "/FL1" is added to their HDF path.
1052 * The ambigious term "pulse" has been replaced by "train" to refer to "pulse train". Most notably, the dataset "/Timing/pulse ID" has changed to "/Timing/train ID".
1053 * A number of inconsistent names have been streamlined. The relevant changes are listed in the following table.
