Preparing the data

adjust raw_data_absolute_path in "params_niklas_fix.py" (line 6) to the raw dsb3 data directory. The raw dsb3 data directory is expected to contain the following folders and files:

• stage1/ (unzipped stage1.7z)
• stage2/ (unzipped stage2.7z)
• stage2_sample_submission.csv

adjust raw_LUNA_absolute_path in "params_niklas_fix.py" (line 7) to the raw LUNA data directory. The directory is expected to contain the following folders and files from the LUNA16 challenge (https://luna16.grand-challenge.org/data/):

• subset0.zip to subset9.zip: 10 zip files which contain all CT images
• annotations.csv: csv file that contains the annotations used as reference standard for the 'nodule detection' track
• sampleSubmission.csv: an example of a submission file in the correct format
• candidates_V2.csv: csv file that contains the candidate locations for the ‘false positive reduction’ track
