Writing SGL array to binary file

I am trying to write a very specific type of binary file in LabVIEW. I need to write an 2D SGL array into the file so that it can later be read and plotted on a waveform graph, but there's always an extra point at the beginning of a file. This extra point presumably comes from the way labview stores array information. How can I get rid of this point at the beginning? I need to alter the writing function, and NOT the reading function. Thank you!
