Hi Marco, Sorry, there is no feature to calculate an average structure. However, EnsembleCluster could be used to cluster the structures and identify a representative for each cluster. This tool is not in the production release from November, but is in the newer daily builds (under Tools... MD/Ensemble Analysis). http://www.cgl.ucsf.edu/chimera/alpha-downloads.html http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/ ensemblecluster/ensemblecluster.html I hope this helps, Elaine ----- Elaine C.

Hi,

I don't know if someone already ask for this... It is possible to calculate an average structure having a bundle of structures? I loaded from the pdb a file containing 30 NMR structures but I would like to use only the mean structure...

Thanks for your help,

Marco
