Thanks for your quick response. This is weird. I am using the correct  d3_q2r.x executable. I have taken a screen shot of the error (I have attached it to this e-mail).</div>

I am also getting a weird result when I call the d3_asr.x executable.  I am getting a lot of "NaN" with no values in the output file (also attached a screenshot of the output file).</div>
