To test whether the difference in AUC/logAUC between two methods is statistically significant or not, AUC/logAUC of the new developed method(s) against the reference method can be compared with bootstrap.
- ligands.name --> file with ligand names to perform enrichment
- decoys.name --> file with decoy names to perform enrichment
- score file(s) --> extract_all.sort.uniq.txt
First, the anaconda python environment needs to be set:
Plot the variation of AUC/logAUC
python /nfs/home/yingyang/work/scripts/bootstrap_AUC.py \ -l ./ligands.name -d ./decoys.name \ -s1 extract_all.sort.uniq.txt \ -p single
The figure will looks like this:
Plot the change(s) in AUC/logAUC against reference score
python /nfs/home/yingyang/work/scripts/bootstrap_AUC.py \ -l ../ligands.name -d ../decoys.name \ -s1 score.standard -s2 score.amber score.freeform \ -p compare
Delta AUC and delta logAUC will be computed and displayed. The p-value from paired t-test indicate if change is statistically significant or not.
