+and save it as ./evaluation_luna16. Note that the official LUNA16 evaluation scripts are based on python2.
+
+To run it with python3, please 1) copy the files in ./evaluationScript_py3_update to replace the files in downloaded scripts in ./evaluation_luna16; 2) then run the following command to convert python2 code to python3 code: `python -m pip install future; futurize --stage1 -w evaluation_luna16/noduleCADEvaluationLUNA16.py; futurize --stage2 -w evaluation_luna16/noduleCADEvaluationLUNA16.py`;
+3) In ./evaluation_luna16/noduleCADEvaluationLUNA16.py, replace `plt.xscale('log', basex=2)` with `plt.xscale('log', base=2)`.
 
 ./evaluation_luna16/noduleCADEvaluationLUNA16.py will be the main python script to generate evaluation scores.
