Delete a channel or channel group in tdms file

[rmi69x]

Hello

I use Labview 8.2.
I want to delete a channel or a channel group in a tdms file. With the Storage VI, I can read the tdms file but the Delete Channel.vi don't work.

I insert my vi.

Thank you.

Hello,

In the Zip file you can found a tdms file and a vi to visualize

Hello Rémi

It is not possible to delete anything out of a tdms file with the VIs from NI, neither channels nor groups nor properties. This is only possible with tdm files. You can create a new tdms file and copy the data you want to keep with the VIs I have posted to the thread http://forums.ni.com/ni/board/message?board.id=250&message.id=27470 and delete the old file after.

I hope this helps

Greetings

This answer is obsolete. There is now a TDMS Delete Data.vi
