Changes in PDB files used for clustering

Release 1.8 has 205 PDB files, release 1.9 has 209 PDB files, 205 of them are identical.

No equivalence class representatives have been replaced.

4 new structures in release 1.9: 4BW0, 4C7O, 4K27, 4LGT.

No equivalence class representatives have been obsoleted.

Help Every Motif Atlas release is based on a representative set of PDB files. When comparing two releases, it's important to know how the input data changed.

Representative sets are quite stable in time, but PDB files from the older releases can be replaced by newer PDB files or removed from the set altogether if the structure is obsoleted by PDB without replacement.

PDB files from the newer release either replace representatives in the existing equivalence classes or come from new equivalence classes.

Changes in motif groups

Release 1.8 has 272 motif groups, release 1.9 has 271 motif groups, 251 of them are identical.

14 motif groups were updated, 7 groups are present only in release 1.8, 6 groups are only in release 1.9.

Help The Sankey diagram shows redistribution of motif instances (loops) between two releases. The rectangles represent the motif groups and are colored as follows:

Added motif groups: green
Removed motif groups: grey
Updated motif groups: orange
Added motif instances: green
Removed motif instances: grey

Hover over the links connecting the motif groups to see which motif instances were exchanged.
