Hi
Yes, I take the following settings in the models.xml file in order to get site operator Sy
<SITEOPERATOR name="Sx" complex="true" site"i">
<PARAMETER name="I" complex="true"/>
(Splus(i)-Sminus(i))/2/I
</SITEOPERATOR>
This setting resembles the standard setting of the site operator Sx in models.xml file
<SITEOPERATOR name="Sx" site"i">
(Splus(i)+Sminus(i))/2
</SITEOPERATOR>
But the error message (cannot evaluate I) reappears, and make the running stop.
As a novice I don't know how to set it in details. Could you help me? Thanks
