sndueste 45.1 30 == The FLASH HDF5 format ==
sendels 1.1 31
sndueste 45.1 32 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.
sndueste 40.1 33
34 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.
35
36 Reference implementation, which follows the concept of Python libraries like Pandas, Xarray, or Dask, is given below.

sndueste 47.1 39 === Comparison to FLASH's deprecated HDF formats ===
sndueste 40.1 40
41 Before 2021, FLASH provided two different HDF formats formally known as //near-online// and //offline// HDF files.
42
43 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.
44
45 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.
46
47 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.

sndueste 71.1 75 * 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}})

402 * The data format of the BAM has been completely altered in the 2022 shutdown
403 * 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 ...
404 * 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)
405 * There has been also a renaming  (and relocation) of the BAMs.
406 ** acc:  4DBC3 → FL0.DBC2
407 ** FL1: 1SFELC →  FL1.SFELC
408 ** FL2: FL2XTDS → (% style="color:#172b4d" %)FL2.SEED5

sndueste 59.1 931 * The data format of the BAM has been completely altered in the 2022 shutdown
sndueste 88.5 932 * 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 ...
sndueste 61.1 933 * 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)
sndueste 59.1 934 * There has been also a renaming  (and relocation) of the BAMs.
935 ** acc:  4DBC3 → FL0.DBC2
936 ** FL1: 1SFELC →  FL1.SFELC

sndueste 33.1 962 * The BAM 8FL2XTDS measures only for FLASH2 BUT has the same data structure as the other BAMS ... thus there are also (random) values in in the  FLASH1 time slot 
963 ** Structure: The first values are for FLASH1 bunches. After a gap of about 70 micros ( 70 colums)  with  as entry for the switching between FLASH 1 and 2 the values for the electrons used in FLASH2 start.  The start time of FLASH2 is also recorded in the DAQ. FLASH1 start time is for historic reasons 700. thus if e.g. the start time of FLASH2 ( property name see below) is 1200 it means that FLASH starts at column 500 (1200-700) ... .In case of doubt ask your local contact

1181 * {{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.
1182 * {{code language="none"}}number of samples{{/code}}: total number of samoles recorded for each 10 Hz trigger

sendels 1.1 1576 === HDF5 structure revisions ===
1577
1578 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:
1579
1580
1581 * All FLASH1 related HDF groups moved to group "/FL1", i.e. a new prefix "/FL1" is added to their HDF path.
1582 * 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".
1583 * A number of inconsistent names have been streamlined. The relevant changes are listed in the following table.
