In TestSets, some knee images filenames has _fix:

$ grep _fix *

None of the knee images extracted with ExtractKnee/preprocessing.py and ExtractKnee/output_00m.csv has _fix in their filename.

Could you provide details of how the knee images with _fix in their filename differ from the correspondent image without _fix in their filename? Thanks!
