Data extraction from an array of data

Question

So I want to extract a
subset from an array of data. 
I have two columns of data that I need to do with,
these are potential energy (expressed in terms of kT) and relative separation.  The data typically results in a parabola-type
shape with the potential energy on the y-axis and the separation on the
x-axis.  The potential energy starts at
high kT's at small separation and then decreases to zero as the separation
increases and then it starts to increase again once it is past zero kT.  The issue I have is that I need to disregard
any data that is greater than 6 kT.  Thus
I need to extract the data (both the potential energy data and the
corresponding separation data) from the array that is 6kT or below.  So the problem I am having is trying to work
out how to approach the extraction of this data.  I would love to get some suggestion as to how
I should approach it.
I initially thought of using a mathscript node to do this,
but I am not sure of how I should code this, if this is indeed possible.
Another option I considered was to use one of the array vi's
to perform this extraction as I thought I could use them to find the element
where the kT is higher than 6 and the corresponding index element which I could
then use to extract the relevant portions of the array.  But I don't see an easy way to achieve this.
So the vi I will write for this will function will actually
be a subvi of another vi I have written (this vi is named ‘non-linear fit to PE
data mod.vi' and it also has a couple of other subvis).  I have attached this vi and a relevant data
file (as an example of the data I will be getting and needing to analyse) in a
zip file.  I haven't included an example
of the subvi I need to write because I looking to find some pointers as to how
I could do this first.  In the ‘non-linear
fit to PE data mod.vi' I have included a text box in the location I will be
putting this subvi.
Any help in helping me out here would be appreciated.
Thanks

Answer 1

Try the attached VI. as per my understanding you want to remove the data in the array which is grater than the specified value,am right?
