trying to use labview to analyse analog data from a jump on a force plate and measure peak force (at two points, initial land and 2nd land from jump). Also need to mark the time of flight (time off plate).

Attached is a file of 3 trials of a drop vertical jump activity onto a force plate. the subject stands on a platform off the force plate, jumps onto the force place and immediately jumps up as if going for a rebound. I am able to run this data and obtain a waveform graph with no problems. however, I need to be able to find the initial contact with the force palte, the peak of the drop, the intial time off the force plate (prior to the jump), the return from the jump and finally the second peak (landing from the jump).

I want to calculate the time of flight ( time off the plate and in the air after the intial drop) to calculate juimp height.

I had someone write me a mathscript for it and it works well, however, I need to do it without mathscript as I do not understand mathscript (nor Labview!!).

Please help

OK, but I'm not understanding what you're asking us to do... Are you asking us to explain what the MathScript code is doing? (It's searching the array for the elements when the values are above or below a threshold.) Are you asking someone to convert the whole MathScript code to LabVIEW (we are not a code-writing service), or you just want to be able to calculate the new stuff you want with LabVIEW?

In the future, please do not post proprietary file formats. Most people do not have Word, or Word 2007 for that matter. Please post text files or PDFs. Thanks.

my apologies! What I need to do is obtain the peak force, time off the force place, etc (the arrows on the graph) by using labview. The mathscript was something someone wrote for me but I can not use it since I am not at all familiar with that language.
