Correcting the impact of docking pose generation error on binding affinity prediction

Hongjian Li, Kwong-Sak Leung, Man-Hon Wong, Pedro J. Ballester
2016 BMC Bioinformatics  
Results: Against commonly-held views, we have found that pose generation error has generally a small impact on the accuracy of binding affinity prediction.  ...  As a result, test set performance after this error-correcting procedure is much closer to that of predicting the binding affinity in the absence of pose generation error (i.e. on crystal structures).  ...  Declaration This work has been carried out thanks to the support of the A*MIDEX grant (  ...
