<p class="MsoNormal">Hello, <o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I am using the SasView software to do SAXS data analysis, and I have a couple of questions. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">When performing the correlation function analysis, is it possible to save the raw data used to generate the correlation function in a text file in order to replot the data?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Also, when I look to perform the invariant calculation, I am loading a .dat file, but the software is unable to generate the 1-D SAXS data plot, and gives an error message when calculating the volume fraction. How can this be resolved?<o:p></o:p></p>
