[Gretl-users] How to exploit the panel data in a SEM

Good day for all. I have a SEM where the structure is panel data. I load the data in gretl, I find options to manage panel data but in the SEM I can't find some option relative to panel data. Is Gretl exploiting the panel data estructure already ? or I have to center the data before to load data on, to manage fixed effect, for example?. I will thanked much your support.
