Bootstrap AUC

Jump to navigation Jump to search

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.

Files needed:

  • --> file with ligand names to perform enrichment
  • --> file with decoy names to perform enrichment
  • score file(s) --> extract_all.sort.uniq.txt

First, the anaconda python environment needs to be set:

source /nfs/home/yingyang/.cshrc_anaconda

Plot the variation of AUC/logAUC

python /nfs/home/yingyang/work/scripts/ \
-l ./ -d ./ \
-s1 extract_all.sort.uniq.txt \
-p single

The figure will looks like this: Variation AUC logAUC.png

Plot the change(s) in AUC/logAUC against reference score

python /nfs/home/yingyang/work/scripts/ \
-l ../ -d ../ \
-s1 score.standard -s2 score.amber score.freeform \
-p compare
