Here, C-score is a confidence score of the GPCR-I-TASSER predictions which
is typically in [-5,2]. TM-score and RMSD measure how close the
model is to the native structure and both are estimated based
on the C-score. TM-score is in [0,1] with a value >0.5 implying
the model of correct topology. The TM-score and RMSD estimations
are made only for the first model because absolute values of
TM-score and RMSD for the lower-rank models do not strongly
correlate with the C-score. The models are ranked based on the
structure density of GPCR-I-TASSER simulations.
The top ten threading templates used by GPCR-I-TASSER
(a) Rank of templates represents the top ten threading templates used by GPCR-I-TASSER. (b) Z-score is the normalized Z-score of the threading alignments. Alignment with a Normalized Z-score >1 mean a good alignment and vice versa. (c) Download Templates provides the 3D structure of the aligned regions of the threading templates.
