nndet_prepare_data_folder script

Prepare Dataset folder according to the nnDetection specifications, creating and populating the subfolders imagesTr, labelsTr, imagesTs and labelsTs. In addition, a JSON instance configuration file (as required by nnDetection) for each label mask is generated, alongside a summary of the train/test split of the dataset. The label mask images are expected to be as instance segmentation masks (NOT semantic segmentation representations).

usage: nndet_prepare_data_folder [-h] -i INPUT_DATA_FOLDER [--task-ID TASK_ID]
                                 --task-name TASK_NAME [--test-split [0-100]]
                                 --config-file CONFIG_FILE [-v | -q]
