What is the impact of c-score and z-score for choosing a best template after doing homology modeling.

Please mention these queries regarding c-score and z-score also kind to mention the range of value that must be highly confidence for the structure to be predicted.

Thanks

Score always means something different, what context did you see these terms? What tool generated the numbers? When we understand what the c and z scores mean, then the answer will be clear.

C-score is a confidence score for estimating the quality of predicted models. It is calculated based on the significance of threading template alignments and the convergence parameters of the structure assembly simulations. C-score is typically in the range of [-5,2], where a C-score of higher value signifies a model with a high confidence and vice-versa.

The Z-score of a protein is defined as the energy separation between the native fold and the average of an ensemble of misfolds in the units of the standard deviation of the ensemble. The Z-score is often used as a way of testing the knowledge-based potentials for their ability to recognise the native fold from other alternatives.

They are self explanatory.
