Try using a for loop and put a threshold, if the value is above threshold then send it out of the loop using conditional terminal.

yr txt s vry rdbl,

on the block diagram hit CTRL+Space and search for "peak", there is a "Peak Detector.vi",

wire your data and give it a threshold, then you will get the x-values for the peaks.
