TDMS Write Custom Properties
Solved!
Properties can be written before, or after the data. Properties are Scalar data, and so a write will replace any data that was there previously. These properties can also be a post test thing. Lets say you didn't know you wanted a Min/Max property until after the test ended. Well you can write a VI that reads each channel, in each group, in each file, and then sets a property that is equal to the min and max of the data. It is usually easier to write properties during the initial creation of the file, but you can do this to update the file afterwards too.
