Understanding Returned DataFrame and Errors

• If there are errors, they will be listed in the DataFrame under an error or message column.
• Review the DataFrame to identify and resolve any issues before reuploading.

CSV Validation Details

Before uploading, the client validates your CSV for:

• Required Columns: Must include study_id, site_id, participant_id, visit_name, visit_order, coa_name, coa_item_number, coa_item_value, file_path, time_collected.
• Optional Columns: rater_id, age, sex, race, language.
• Valid COA Name: Only these values are allowed: MADRS, YMRS, PHQ-9, GAD-7.
• Valid Audio File: The file path in each row must exist and be accessible.
• Valid Data Types: visit_order, age, coa_item_number, and coa_item_value must be numeric.
• Language: If present, must be in the allowed language choices.

If any validation fails, errors are collected and returned for review before upload proceeds.
