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.
Fragment Score: Scans for parts of your design that are unlikely to fold up naturally. Use Rebuild and Remix tools to fix these regions 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. Also penalizes hydrophilic residues in the core and hydrophobic residues on the surface.
