Opening multiple data files¶
It is possible to open multiple *.dmd data files and to review them (from OXYGEN 6.0). The data files must currently belong to the same OXYGEN-NET recording.
In order to open several files, click on the folder icon in the Action bar and select all files to be opened and reviewed. The files must be within the same folder.
In order to open several files, there are two options. Click on the folder icon in the Action bar (see Fig. 482) or open the full menu of the Measurement Settings > Analysis Files and click on Add file… (see Fig. 481) and select all files to be opened and reviewed. The files must be within the same folder.
The single files with all the channels are available in the Channel List and shown as individual sections.
All channels from each file can be used for offline math and visualized on the measurement screen. A new data file can be stored, including all channels from each file (see ⑬ in Fig. 10).
Single files can be removed again, by clicking on the X, by opening the menu of the Measurement Settings (see Fig. 484). By clicking on the circled i, more information can be displayed for each file.
The data files must currently belong to the same OXYGEN-NET recording.
The data files must be in the same folder. It is not possible to select files from different folders.
Changes, which were done in a measurement file during analysis and post-processing can also be applied to other measurement files. This can be very useful when having measurement series or campaigns, where changes can then be applied to all files. The same setup must have been used for all files and all files must include the same recorded channels, to apply the changes. Following changes will be applied:
Offline math (formulas, power groups, etc.)
Offline changes in the channel list (CAN channels, etc.)
Changes to the measurement screen (instruments)
To do so, simply open one measurement file. After doing the analysis and post-processing save the file, open the full menu of the Measurement Settings and go to File History (see Fig. 485). By clicking on the Button Apply changes to other measurement files… the files can be selected from the dialogue which will open (see Fig. 486). Files within the same folder can be selected.
After selecting the files, click Open and a new dialogue will open (see Fig. 487). To apply all changes press Start. Fig. 487 shows the dialogue after the processing is done to all files successfully.
The dialogue will also show any errors, in case the processing cannot be fulfilled. These files will be ignored, in case the processing is started anyway.
Possible reasons for this could be:
File not accessible and cannot be opened, because it might be already open.
Channels are not the same for each file. This file might not be recorded with the same *.dms setup such as the other files.
To return to your original file or later revision, click on the corresponding button under Rollback file change seen in Fig. 485. The changes made to the file will be deleted.
