Item Description
The precision of each cluster or ensemble is calculated as dRMSD, which
is the average C-alpha distance root mean square deviation (dRMSD)
between the individual models in the cluster and the cluster centroid.
The cluster centroid is defined as the model with the minimal sum of
dRMSDs to the other models in the cluster or ensemble.
