Missing functionality if storing TDSM from LabVIEW

[bilik]

In DIAdem File Browser window is selected a file from DIAdem 11.0 Examples directory. File FFT_Expl_1 has icon with „tree pictogram“ and „tree pictogram“ can be expanded to see content of file (Time, Oscillation), bellow of File Browser is displayed many file properties. Anyway these properties are not displayed in DataPortal area?!? See picture 1.

 
Pict. 1

If I click on the file content in tree hiearchy channel Oscillation I can see properties for this channel and small graph with the signal preview. See picture 2.
 
Pict. 2
 
To make my own data I have used examples from LabVIEW 8.6. One of these is on the picture 3 TDMS - Express write data (time and frequency domain).vi.
 
Pict. 3

Every time I create TDMS data from LabVIEW 8.6 (it doesn’t matter which example I use) I see in DIAdem File Browser instead of tree icon the question mark icon?!? The question mark icon cannot be expanded by clicking on it?!? Also the amount of Shown properties is significantly lower in comparison with DIADem example files. Also no signal preview is displayed?!? How to proceed with LabVIEW and TDMS function to have possibilities of DIAdem example files?

 
Screenshots are in attached DOC file. 

Please help

Hello bilik,

Thank you for the great description of your problem, the Word document with the screen shots really helps with the troubleshooting.

It looks to me as if you haven't indexed the directory where your TDMS files are stored. The "?" icon indicates that the file is not indexed. If a file is not indexed, only a subset of the properties are shown in the dialogs.

The easiest way to solve this issue is to index the directory that contains you data files (your directory icons are grey, they should be yellow). This can be done by going to the directory (or subdirectory) in the DIAdem NAVIGATOR window, and right clocking on the directory name. From the context menu, select the function "Add Search Area ..." - your directory will then be transferred to the Search Areas part of the NAVIGATOR and all the TDMS files will be indexed. At the point the files will show all the properties and the "?" will disappear.

Let me know if that helped,

Hello Otmar,

thanks a lot. Your answer solved my problem.

Anyway maybe you can help me with another problem connected more with LabVIEW and TDMS, but data will be processed in DIAdem:
