TDMS properties "alias-list" ??

[B_Wagner]

Hi all,

I'm using the TDMS format to import my Labview Data into Matlab. To
read out the main root, group and channel properties I simply copied
the respective parts of the 'ReadTDM' example taken from the NI-
support home page and everything works fine.

While checking my recordings with the Excel-plugin I recognized that
there are several other properties of interest stored , but which I
don't know how to adress in my "DDC_FILE_ ..." commands (Sample clock
rate, min/max values, etc.) .

My question: Is there a list or manual how to adress these extra
properties? I tried some variations of the names shown in Excel (like
DDC_FILE_SAMPLECLOCK.Value) but this didn't work out.


thanks in advance for any hint

Hi B_Wagner,

Where did you find the ReadTDM example?  Is this the one?  Regardless, the available properties should be listed within the header file (nilibddc.h for example).  If you do not see commands to retrieve the information that you want (sample clock, min/max, etc...), then you may have to manually code functions to retrieve that data.  Also, to clarify, are these the properties that you're referring to?

Hi Pakman,

sorry for the late answer. After quite some time without response to my question I quit checking the forum (and appearently the email-alert doesn't work for me........whatever).

Yes, my example is the one you linked, I should have specified that, sry. And you marked exactly the properties I'm interested in.

Thanks for the hint concerning the header file. I checked the nilibddc.h and found, that min/max are already listed within whereas for the interval I'll have to do some coding. I'm on it atm and it seems to work. 

Thanks again ,
