Export Settings¶
Fig. 526 Export Settings – Overview and export options for a *.csv-file¶
In PLAY mode, the user can export the recorded data into the following formats:
*.csv-file
*.txt-file
*.mdf4-file
*.mat‑file
*.xlsx-file
*.rsp (rpc III)-file
*.wav-file
*.dat-file (DIADEM)
*.nt-file (DynaWorks)
*.h5-file
*.uff-file (Universal File Format 58; Binary and ASCII)
*.imc-file (FAMOS)
*.tdms-file (LabVIEW)
*.nc-file (NetCDF)
*.datx-file (DSPcon)
The user can select the channels to be exported in the channel list displayed in the Export Settings (Fig. 526).
Export active recorder region or between cursors¶
The user has the possibility to only export the active recorder region of the selected recorder or the region between the cursors. Depending on whether the cursors are activated one of the following options to export (see Fig. 527) can be seen. This option is available for all file formats.
Fig. 527 Export active recorder region or between cursors¶
Note
These options are only available if the export menu is not enlarged and opened to full size. If the menu is enlarged to full size or these options are deactivated the whole recorded data will be exported.
Export triggered data file with trigger aligned to zero¶
Fig. 528 Align timestamps in exported file to zero¶
Timestamps in an exported data file with a triggered event can be aligned to the trigger (see ① in Fig. 528). If align to trigger is not selected, then the 0s timestamp will be at recording start, not at the trigger (see ② in Fig. 528). If align to trigger is selected, the timestamp at the trigger will then be set to zero. Thus, the time leading up to the trigger event (e.g. the pre-time) will be negative (see ③ in Fig. 528).
If more than one trigger event is in a recording, then the first trigger event will be set to zero, when the align to trigger option is selected.
This option is possible for *.txt, *.csv and *.xlsx-export.
Export Options for a *.csv-file¶
If *.csv is selected as format, the user has the following additional options (see Fig. 529):
Fig. 529 Export Options for a *.csv-file¶

Select the decimal precision from 1 to 20 digits; the decimals will be rounded to the selected precision
Selection of Separate header row for units will write the units in a separate row below the channel names
Select Use absolute timestamps or export relative timestamps
Waveform: select if the waveform data shall be exported.
Fill data gaps: select if data gaps shall be filled up when exporting channels with different sample rates. For channels with a lower sample rate, the samples will be repeated until the next sample is available.
Statistics: select which of the statistics parameters shall be exported
Export Options for a *.txt-file¶
If *.txt is selected as format, the user has the following additional options (see Fig. 530):
Fig. 530 Export Options for a *.txt-file¶
Choose between Decimal separator ‘.’ and ‘,’
Select the decimal precision from 1 to 20 digits; the decimals will be rounded to the selected precision.
Selection of Separate header row for units will write the units in a separate row below the channel names
Select Use absolute timestamps or export relative timestamps
Waveform: select if the waveform data shall be exported.
Fill data gaps: select if data gaps shall be filled up when exporting channels with different sample rates. For channels with a lower sample rate, the samples will be repeated until the next sample is available.
Statistics: select which of the statistics parameters shall be exported
Select if the Header fields shall be exported to the file
Select if the Event List shall be exported to the file
Select if the Recording start and the Recording duration shall be exported to the file

If *.mat is selected as format, the user has the following additional options (see Fig. 532):
Fig. 532 Export options for a *.mat-file¶
Choose between Compressed and Normal export
The exported file format is a 7.3 MAT-file
Compressed: The *.mat-file will be compressed during export. Thus, the Compressed export will take more time than the Normal export
Normal: The *.mat-file will not be compressed during export. Thus, the Normal export will be quicker than the Compressed export, but the resulting *.mat-file is larger
Events and Header data will be exported per default. The check boxes are only displayed for information purpose
Select if Waveform data and/ or Statistics data shall be exported
Export options for an *.xlsx-file (Excel)¶
If Excel is selected as format, the user has the following additional options (see Fig. 533):
Fig. 533 Export options for an Excel-file¶
Selection of Separate header row for units will write the units a separate row below the channel names
Select Use absolute timestamps or export relative timestamps
Waveform: select if the waveform data shall be exported.
Fill data gaps: select if data gaps shall be filled up when exporting channels with different sample rates. For channels with a lower sample rate, the samples will be repeated until the next sample is available.
Select if a new spreadsheet should be created per file (for multi-file recordings) or per event (for triggered recordings). Otherwise select no split.
Note
As the number of lines on one Excel spreadsheet is limited to 1048576 (220) the data will be written to a new spreadsheet if this limit is reached.
Export Options for a *.rsp (rpc III)-file¶
Fig. 534 Export options for a *.rsp-file¶

Batch export¶
OXYGEN’s Batch export option provides the possibility to automatically export several *.dmd-files successively with the same export settings. To do so, open the first *.dmd-file that shall be exported and go to the Export menu.
Fig. 544 Export menu¶
Select the desired export format (including the individual options) and the channels to be exported (see ① in Fig. 544). Press the Batch Export button next (see ② in Fig. 544).
A popup window will open that allows the user to select other *.dmd-files whose data shall be exported with the same export settings that are selected for the first file (see Fig. 545). After selecting all desired files, press Open.
Fig. 545 Popup window to select additional *.dmd-files for export¶
The batch Export menu will open listing all selected *.dmd-files (see Fig. 546). The destination folder for the exported files can be specified.
Fig. 546 Batch Export menu¶
Three additional options can be selected :
Overwrite existing files
Continue after error
Export all channels
Press Start to initiate the batch export. The progress will be displayed while the export is running. The export file name will be equal to the *.dmd-filename.
Fig. 547 Batch export window after export is finished¶
After the export is finished (see Fig. 547), the Batch Export window can be closed.
Note
In case only certain channels shall be exported the selected channel’s names must be the same in all *.dmd-files. Alternatively. It is possible to export all channels from the selected files.
All *.dmd-files that are selected for the batch export must be in the same folder.
Each *.dmd-file is exported into one separate file.
Data is always exported from measurement start to measurement end. Active recorder/cursor regions will be ignored.
Errors occurring during the export could be the following:
Channel not found: A channel that is selected for export is not included in one of the *.dmd-files
File not accessible: A *.dmd-file is open in another OXYGEN Viewer
Export file already exists
The batch export will stop in case an error occurs but it is possible to continue with the export in case the option Continue after error is selected.
The file for which an error occurs will be skipped during the batch export.
