++== FLASH HDF5 structure ==
++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:
--[[Contents>>doc:||anchor="Contents"]]

++* Timing
++[[image:url:http://hasfweb.desy.de/pub/Setup/HDF5main/HDF5_structure.jpg||alt="HDF5_structure.jpg" width="700" height="500"]]
--== The FLASH HDF5 format ==
++A detailled description of (most) channels can be found in the lower part of the hdf5 viewer:
++[[image:url:http://hasfweb.desy.de/pub/Setup/HDF5main/HDF5_structure_desc.jpg||alt="HDF5_structure_desc.jpg" width="341" height="413"]]
--FLASH provides a conversion of its data acquisition (DAQ) to the commonly used [[HDF5>>url:https://www.hdfgroup.org/solutions/hdf5/||shape="rect"]] format. Correlated  data are mapped by a primary index called **train ID**. Every data set has an individual index of train IDs to identify the data even when data are missing or deviate in update rate. If the data set of choice contains gaps,  users have to decide how to treat missing values. DAQ channels are spread across various files with one file name pattern for each DAQ. This means users have to assemble data from different files if necessary.
++\\
--The hierarchy is realized using a human readable named HDF tree with each DAQ channel containing the data sets "//value//" and "//index//". Additionally, the HDF group //zraw// contains a tree of the original DAQ channel names.
++\\
--Reference implementation, which follows the concept of Python libraries like Pandas, Xarray, or Dask, is given below.
++== Most popular FLASH parameters and their names in HDF5 ==
--{{expand title="Discontinued HDF formats"}}
--=== Comparison to FLASH's deprecated HDF formats ===
++The compleate list for the relation between DOOCS names and HDF5 names for the recordable parameters can be found in [[DESY's Repository~[~[image:url:http://hasfweb.desy.de/pub/TWiki/TWikiDocGraphics/external-link.gif~|~|width="13" height="12"~]~]>>url:https://stash.desy.de/projects/CS/repos/pah/browse/src/camp/data/channel2HdfName.dat||shape="rect"]].
++The most common and often used ones are summarized below:
--Before 2021, FLASH provided two different HDF formats formally known as //near-online// and //offline// HDF files.
++Note, the HDF group and dataset names apply to our HDF tree version since vers. 0.3.0.
--All data sets were aligned by the same global index by filling in missing data. Fast DAQ channels  (pulse synchronous data - update 10 Hz) are filled in by NaN or 0, slow channels (not pulse synchronous data - update e.g. 1 Hz ) are interpolated by the DAQs libraries, by keeping the value constant up to the next change.
++\\
--While the near-online HDF files were converted live during the beamtime, the offline HDF files were manually compiled weeks/months later. Near-online HDF files were used by a provided API [[BeamtimeDaqAccess>>url:https://confluence.desy.de/display/FLASHUSER/Near-Online+data+analysis#Near-Onlinedataanalysis-BriefUserGuidetoBeamtimeDAQAccess||shape="rect"]], which also searches for DAQ channels in files. With assembled files "by run", all DAQ channels were existing in the same HDF file. While shorter runs usually fitted into one file, longer runs still had to be aggregated over several files. The creation of the assembled type of files still involves the use of fairly unstable DAQ Mex-functions As the environment required for using the Mex-functions is already deprecated, its continued existence is uncertain.
--
--The HDF hierarchy is almost identical in all formats. While in the the recent format each DAQ channel contains the data sets "value" and "index", the deprecated format had one data set for each DAQ channel. The deprecated formats supplies no time axis parameters for spectra data types.
--
--
--**HDF5 example files (old format)**
--
--Here we have a few HDF5 samples (User data combined with Photon diagnostics data) from a few beamtimes showing the different kind options.

--* The //average// FEL pulse energy as example for the **slow** **data**. Here the data is not saved with 10 Hz  - thus not for every FEL pulse train.  The data is typically saved with 1 Hz if the values are changing (like the FEL energy) and every about 20 sec if there is no change for longer time ( e.g. motor set values). Thus to use the data together with the "fast" one, one has to interpolate the data as explained in the examples in the repos below show (e.g. {{code language="none"}}df['GMD_T_average'] = df['GMD_T_average'].interpolate(method='linear'){{/code}})

--* The data format of the BAM has been completely altered in the 2022 shutdown
--* before 2022 BAMs were always saving the arrival time information for each 1µs bucked regardless if there were electrons in the accelerator or not. IN addition the arrival times for  FL1 and FL2 were saved in the same parameter ...
--* THIS is now different. There are new parameters saving only the arrival times for pulses that go to FL1 and to FL2 (in detail: first time slot of the accelerator and second)
--* There has been also a renaming  (and relocation) of the BAMs.
--** acc:  4DBC3 → FL0.DBC2
--** FL1: 1SFELC →  FL1.SFELC
--** FL2: FL2XTDS → (% style="color:#172b4d" %)FL2.SEED5

--* There has been also a renaming  (and relocation) of the BAMs.

--==== User Data (FLASH2) ====
--
--The data saved specifically for detectors at an experiment will show up in /Experiment/ there is a large number of options for cameras or monitoring pslow properties (motor positons etc) for user experiments. For details please ask your local contact.
--
--NOTE: If parameters for an experiment are included on short notice the correct naming in the HDF5 may not be in time and the data will show up in /uncategorized/ with the DOOCS names
--
--The most common and permanently installed device used by experiment are our ADCs:
--
--===== GHz ADCs =====

--ADC traces of the (SPDevices 412) GHZ ADCs available for the users . More information about the ADCs can be found** [[here>>doc:FS-FLASH USER tmp.Data Acquisition and controls 1.Controls (DOOCS, jDDD,\.\.\.).MTCA ADCs.WebHome]]**

--here the {{code language="none"}}CH00.TD{{/code}} is the full ADC trace as it is sampled ( typically several 100.000 samples per pulse train) while the {{code language="none"}}CH00.DAQ.TD{{/code}} trace only has the number of samples which are sent to the DAQ OR if //grouping// is activated the {{code language="none"}}CH00.DAQ.TD{{/code}} conatins only the grouped spectra. To read the ADC trace with an online analysis program the {{code language="none"}}CH00.DAQ.TD{{/code}} is used preferablly.
--DAQ channel: {{code language="none"}}FLASH.FEL/ADC.ADQ.FL2EXP1/FL2EXP1.CH00{{/code}}
--
--In addition there are also additional parameters saved like:
--
--* {{code language="none"}}sample frequency{{/code}}: it shows the sample frequency in MHz (number of samples per µs). NOTE: the clock of the ADC is NOT synchronized to the FLASH timing system. Thus the number of samples between bunches in the bunch train may be not integer numbers which will be show up for long bunch trains.
--* {{code language="none"}}number of samples{{/code}}: total number of samoles recorded for each 10 Hz trigger
--* {{code language="none"}}error (ADC):{{/code}}0 indicates that there was no error
--* {{code language="none"}}/CH0-CH3/offset{{/code}}: To use the full dynamic range of the ADC one can shift the base line . This offset is saved here.
--
--===== MHz ADCs =====
--
--similar to the GHz ADCs the MHz ADCs are saved with HDF5 names like:
--{{code language="none"}}/FL2/Experiment/MTCA-EXP1/SIS8300 100MHz ADC/CH2/TD{{/code}}
--DOOCS prop : FLASH.FEL/ADC.SIS.FL2EXP1/FL2EXP1.CH02/CH00.TD

--

  === HDF5 structure revisions ===
  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:
++\\
  * All FLASH1 related HDF groups moved to group "/FL1", i.e. a new prefix "/FL1" is added to their HDF path.
  * 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".
  * A number of inconsistent names have been streamlined. The relevant changes are listed in the following table.
