could you attach the file you are reading from? The issue could be with that. Also, no need for a local variable, just split the sampling frequency wire. You are creating a race condition. If the user updates the control, there is a possibility (which is more than likely) that the local variable will be read first and then if the control value changes you will get a different value going into your filter than that which is used in the division. To see an example, use highlight execution and change the sampling frequency value AFTER you see that the local is read. You will see the variable value doesn't equal the control value going into your filter.
Also, the index array function is expandable. You don't need two of them, you can instead click and drag the bottom of the VI and it will expand to take more indexing inputs. Hover your mouse over the VI and you will see.
That's just some cleanup stuff. Like I said, post your text file if you can. Thanks!
