<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Sorry that I wasn't clear about the data file. The "Loc" DataArray is not included in the original data. I simply copy&paste the "Position" DataArray and re-named it "Loc" in order
to find data based on its location. This is a workaround and it works just fine for small data files. However, my original data is quit huge and I have to do the copy&paste for thousands of files to make the workaround work. Also file size will be increased
significantly by using this method. Since the "Position" information is already included in each data file. I am wondering if there is a way to access it in "Find Data". If so, I don't need to replicate it to create "Loc".<o:p></o:p></p>
