Predicted contact map used in C-I-TASSER simulation

C-I-TASSER simulation is guided by consensus contact map (upper left triangle) derived based on confidence scores of TripletRes (lower right triangle), ResTriplet, ResPRE, and NeBcon. In the contact map, the axes mark the residue indexes along the sequence, while each dot represents a residue pair with predicted contact. No dot is close to the diagonal, because C-I-TASSER does not consider contacts for residue pairs separated by <6 residues.

(a)	ID1 is the number of template residues identical to query divided by number of aligned residues.
(b)	ID2 is the number of template residues identical to query divided by query sequence length.
(c)	Cov is equal the number of aligned template residues divided by query sequence length.
(d)	Norm. Zscore is the normalized Z-score of the threading alignments. A Normalized Z-score >1 means a good alignment and is highlighted in bold.
(e)	Download alignment lists the threading program used to identify the template, and provide the 3D structure of aligned regions of threading templates (threading[1-10].pdb.gz).

(a)	C-I-TASSER simulations generate a large ensemble of structural conformations, i.e. decoys. These decoys are clustered by SPICKER based on pairwise structure similarity to report up to five final models from the five largest clusters. Models are ranked in descending order of cluster size. If the simulations converge well, it is possible to have less than 5 models generated, which is usually an indication of good model quality.
(b)	The model confidence is quantitatified by C-score, calculated based on significance of threading template alignments and convergence of C-I-TASSER simulations. C-score is typically in the range of [-5, 2], with higher C-score signifies higher model confidence.
(c)	Model TM-score and RMSD are estimated based on C-score and protein length for the first model.
