Join files in sequence

I have around 12 TDMS files for each set of experiments. Each files builds on the previous in terms of wear. So i need to join all these 12 files in proper sequence so that when I need to run a script I dont run it on 12 individual files and then join them later.

 

Is there a way this can be done?

Hi hmurya,

 

read those 12 files one after the other and save them all into a 13th file…

Best regards,

I did that. But it still saves as 12 different channels within a file so when I run a script in Diadem it runs on a single channel. I want it all to be one whole file. Unless I am doing something wrong 😕

That's probably the problem: you are doing something wrong - by not attaching your VI…

You might attach your VI so we could troubleshoot it!

Hi hmurya,

 

you wrote:

So I guess you created some kind of VI to actually do "I did this"…

Read all  the TDMS Files and write them in different TDMS File, post the code which you have tried.

Ok so I am a bit lost. I have attached two tdms files as examples. How would i go about joining them and not having the other smaller valued channels?

Hi hmurya,

 

the TDMS File monitor shows this:

You need to load just the first signal (first group, first and only signal in group) of each file and save it to a new TDMS file:
