<div class="markdown level1 summary"><p>This function parses the values given for the ROIs with the argument
-Rroi. Currently only circular and rectangular ROIs are supported.</p>
<pre><code>       &lt;p&gt;A rectangular ROI is indicated by a 'R' followed the coordinates for
       the upper left corner of the ROI and then its width and height.&lt;/p&gt;&lt;p&gt;A circular ROI is indicated by a 'C' followed by the coordinates of
       the circle center and then the radius.&lt;/p&gt;&lt;p&gt;Before the R and C values, the component that are affected by the
       ROI are indicated.&lt;/p&gt;
