Residue IE Score: Monitors that all PHE, TYR, and TRP residues are scoring well.

Core Existence: Ensures that at least 30% of the residues are buried in the core of your design.

Secondary Structure: Checks that no more than 50% of residues are in helices; penalties are incurred if more than 50% of residues form helices.

Secondary Structure Design: Penalizes all CYS residues. Penalizes GLY, ALA, and PRO residues in helices and sheets.

Residue Count: Penalizes extra residues inserted beyond the 85 residue limit. Players may insert up to 10 extra residues.

Ideal Loops: Penalizes loops that do not conform to preferred ABEGO patterns. Use Auto Structures to see which residues count as "loops."

I have a blue-blue-blue helix to helix loop, which is accepted by the ideal loop filter. In fact I made it by defining 3 segments as sheet and running ideal SS on the segments. But this color pattern is not in the list of ideal helix-helix loops shown in the Rama map.

Is this pattern missing in the list of of ideal loops or is it a mistake by the ideal loop filter?
