Krivan,
I think another problem with your average vi is that you are not updating the start point of where you read from, you will always be reading from 0. Unless you have count to -1 that is read all then you will just loop continually reading the same data. Also, you have no logic to exit the loop when you have read all data, you are just relying on a stop button. what happens when you do get to the end of the file? I have never used the TDMS vi's but i would imagine that you will need to start at 0, read x amount of lines and increment the index accordingly, passing this through a shift register to the next read. When you have finished (possibly by seeing if the TDMS read outputs and empty array) then exit.
