Write to spreadsheet in loop

[mares_wyo]

I am trying to write waveform data to a spreadsheet.  Currently, I am acquring and filtering data in a loop.  I was advised that the best way to write data to spreadsheet based on a front panel boolean switch is to use paralled loops.  I tried this, but my program only hits the acquisition loop.  How can I do this with parallel loops.  Is there any examples?  I have attached my VI with only the acquisition loop. 

Thanks,

I have added a queue to your code.  This will allow the DAQ data to be moved from your main loop to the "file IO loop" without interrupting your main program anda filtering.

Let me know if you have any questions on this.  There are example programs on queues as well as documentation in LV help if you want to do a little more research.
