I am trying to read a TDMS file with 60 channels, extract 12 of the channels containing the data I am interested in. This I have done successfully and been able to manipulate that data how I need. Where I am struggling is there are 4 specific channels in that set of 12 that contain the trigger. One of those 4 needs to trigger my data processing depending on which one contains the voltage spike. I am struggling to be able to find which one of the 4 channels has the spike then use that channel to set the offset and sample length of the remaining channels.

Hi Nate,

So you have to analyze upto 4 channels to look for those spikes. (Can there be more than one channel that acts as trigger?)

Do you struggle with finding the spike in your channel data?
Do you struggle with analyzing the spike?
Do you struggle with applying "offset and sample length" to the other channels?
Btw. is this a real question at all or just a copy from some other forum message? Can you provide (stripped down example) TDMS data?
