&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The ellipsoid.model file is used to specify the parametric model that [[GenCoords]] uses to arrange a set of ellipsoids in a starting pattern. The file has the following format:&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
*&amp;#039;&amp;#039;modelType&amp;#039;&amp;#039; specifies which of the [[GenCoords Models]] is to be used define the distribution of ellipsoids.&lt;br /&gt;
*&amp;#039;&amp;#039;np&amp;#039;&amp;#039; is the number of parameters needed to drive that model. &lt;br /&gt;
*&amp;#039;&amp;#039;nc&amp;#039;&amp;#039; is the number of clusters&lt;br /&gt;
*&amp;#039;&amp;#039;ne&amp;#039;&amp;#039; is the number of ellipsoids in each cluster. &lt;br /&gt;
*&amp;#039;&amp;#039;aMult&amp;#039;&amp;#039; is a scaling factor for the attractive [[PY]] potential and is dumped into the 4th column of the [[pysites.xyz]] file. &lt;br /&gt;
*&amp;#039;&amp;#039;rMult&amp;#039;&amp;#039; is a scaling factor for the repulsive [[PY]] potential and is dumped into the 5th column of the [[pysites.xyz]] file.&lt;br /&gt;
*&amp;#039;&amp;#039;param1, param2,... , paramNp&amp;#039;&amp;#039; are the n parameters needed by that model and are model specific.&lt;/div&gt;</summary>
