--== The FLASH HDF5 format ==
++== FLASH HDF5 structure ==
--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 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:
--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.
++* Electron Diagnostic
++* Photon Diagnostics
++* Beamlines
++* Experiment
++* Timing
++[[~[~[image:url:http://hasfweb.desy.de/pub/Setup/HDF5main/HDF5_structure.jpg~|~|alt="HDF5_structure.jpg" width="700" height="500"~]~]>>attach:HDF5_structure.jpg]]
--Reference implementation, which follows the concept of Python libraries like Pandas, Xarray, or Dask, is given below.
++A detailled description of (most) channels can be found in the lower part of the hdf5 viewer:

--=== Comparison to FLASH's deprecated HDF formats ===
++[[Contents>>doc:||anchor="Contents"]]
--Before 2021, FLASH provided two different HDF formats formally known as //near-online// and //offline// HDF files.
++\\
--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.
++== Most popular FLASH parameters and their names in HDF5 ==
--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 complete 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:
--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.

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

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

This one was newly installed in 2020.. The property contains only the arrival time of the bunches sent to FL2 (e.g. if there are 30 bunches in FL2 the first 30 values are the arrival time the remaining numbers still may have arbitrary numbers looking like a signal which they are not). These are the same values as the "raw" data below - just "cleaned". The values show a very good correlation to the arrival time  of the XUV pulses in the experiment (see help).

--desc: Electron bunch arrival time measured  with the BAM  before the undulator (pulse resolved data). This one was newly installed in 2020.  Here the complete bunch train from the FEL is recorded (FLASH1 and FLASH2 pulses). Thus there are values from FLASH 2 in the second part. they may be separated by several "0" values if the reprate is different from 1 MHz ...   - It shows a very good correlation to the arrival time  of the XUV pulses in the experiment (see help).

--desc: The max 600 µs acceleration time of FLASH is devided between FLASH1 and FLASH2. This 600 µs window starts with FLASH1 (up to now)  at a time"label" of 700 µs (for historic reasons). Thus the first bunch of FLASH 1 comes at "700" and the last possibel bunch comes at 1300 (700+600). After FLASH1 train is over ther is a about 70µs switching time with no bunches. Then comes the first FLASH2 bunch.  Thus if e.g. the start time of FLASH2 is 1200 it means that FLASH2 starts at column 500 (1200-700)  in the HDF5 files. (However for yet unknown reasons this may change by 2-3 colums ...)

--==== 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:

--In addition there are also additional parameters saved like:

  === 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.
