How to release and read another external file

Question

My vi is set to read an external file (a previously collected force plate signal), then perform a string of analyses on it and finally save the analytical output. Currently, "Read from measurement file" is outside the while loop containing all of my analysis.
Without completely restarting the vi, I would like to be able to release the file and load another.  How might I do this?  
Thanks!

I would do several things to clean up the block diagram.
whenever you have multiple outputs that are related to each other (PF, F100, F150, F200, F250, etc...) or all of the RFDs and Impulses, you can bundle them together and then display them with one big cluster, or as an array, if that makes sense.  This will reduce your total number of outputs and maybe improve organizaiton.
If you have a seqeunce of functions that go together, you can combine them into a SubVI to save blockdiagram space and making things more logical.
If you have several places where the same sort of function is being done, (for example, you have Extract-Statistics-Formula several times and Extract-Integral-Statisics several times) you can make this into a sub-VI and then loop through it.  That way you can execute the function multiple times (with slight changes on each loop), but you only have to have the code written once. It also makes it much easier to improve the code because you only have to make one change instead of four. 
The attached VI shows two ways of doing something.  On the left is your code, which is four sets of the same thing.  On the right, I've taken this code and put it into a loop so it does the same thing four times.
