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 can go to 95 residues

Bruno, yes you can but the penalty for adding residues over 85 should quickly deter you from doing so. I noticed a 10000 point penalty for 95 residues.

This is the slowest puzzle I've worked on recently. It takes my PC as long as 10 minutes to grind through 3 iterations of wiggle. The fact that I'm on the scoreboard at all is only due to my stubbornness.
