Hi Lucio,
Sorry, Chimera doesn't calculate an average structure from an ensemble.  However, "Ensemble Cluster" (in the menu under Tools... MD/Ensemble Analysis) will give clusters, and for each cluster, the best representative.  That's not exactly what you asked for (the one best representative), but may be worth a look:


This tool is also used in the "Model Panel and Ensembles" tutorial:

I hope this helps,
