GI-DAMPs

The GI-DAMPs pipeline pulls sampling records from the IGMM REDCap server, removes direct identifiers, and reshapes the data into tidy assets that Dagster can materialise. The cleaning step standardises column names, coerces numeric and date types, maps categorical codes to readable values, and prepares derived fields such as medication flags and disease activity indicators. Refer to the code below whenever you need to confirm how a specific variable is constructed before it lands in G-Trac.

    5. Drops specific columns from the 'sampling' and 'cucq32' DataFrames.
    6. Renames the 'cucq_date' column to 'sampling_date' in the 'cucq32' DataFrame.
    7. Merges the 'sampling' DataFrame with the demographics DataFrame on 'study_id'.
    8. Merges the resulting DataFrame with the 'cucq32' DataFrame on 'study_id' and 'sampling_date'.
    Note:
        The function assumes that the input DataFrame contains the columns 'redcap_repeat_instrument',
        'study_id', 'cucq_date', and other columns mentioned in the code.
