This pipeline extracts the NWICU dataset (from physionet, https://physionet.org/content/nwicu-northwestern-icu/0.1.0/) into the MEDS format.

pip install NWICU_MEDS
export DATASET_DOWNLOAD_USERNAME=$PHYSIONET_USERNAME
export DATASET_DOWNLOAD_PASSWORD=$PHYSIONET_PASSWORD
MEDS_extract-NWICU root_output_dir=$ROOT_OUTPUT_DIR

When you run this, the program will:

1. Download the needed raw NWICU files for the currently supported version into $ROOT_OUTPUT_DIR/raw_input.
2. Perform initial, pre-MEDS processing on the raw NWICU files, saving the results in $ROOT_OUTPUT_DIR/pre_MEDS.
3. Construct the final MEDS cohort, and save it to $ROOT_OUTPUT_DIR/MEDS_cohort.

You can also specify the target directories more directly, with

export DATASET_DOWNLOAD_USERNAME=$PHYSIONET_USERNAME
export DATASET_DOWNLOAD_PASSWORD=$PHYSIONET_PASSWORD
MEDS_extract-NWICU raw_input_dir=$RAW_INPUT_DIR pre_MEDS_dir=$PRE_MEDS_DIR MEDS_cohort_dir=$MEDS_COHORT_DIR

You can run MEDS_extract-NWICU --help for more information on the arguments and options. You can also run

MEDS_extract-NWICU root_output_dir=$ROOT_OUTPUT_DIR

to run the entire pipeline.
