Rank
In each cluster, the chains are sorted (i.e. ranked) according to the following criteria (in this order):
- A simple quality factor, calculated as
1/resolution - R-value
- Deposition date (newer structures have higher ranks)
- Alphabetically
This ranking has the following implications:
- Higher quality structures (better resolution, lower R-value) are preferred.
- Structures determined by X-ray crystallography are preferred over NMR structures.
Cluster ID / Name
The internal number of the sequence cluster used for unique identification.
