-Sample task configuration files for 6 common tasks are provided in `sample_configs/`. All task configurations can be directly extracted using `'direct'` mode on `sample_data/sample_data.csv` as this predicates dataframe was designed specifically to capture concepts needed for all tasks. However, only `inhospital_mortality.yaml` and `imminent-mortality.yaml` would be able to be extracted on `sample_data/esgpt_sample` and `sample_data/meds_sample` due to a lack of required concepts in the datasets.
