Issue Log:
Error: An empty value or a null value was detected in ["COLLECTION"]["ADDITIVES"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "none", in ["COLLECTION"]["BLOOD_SERUM_OR_PLASMA"] should be one of "Blood", "Plasma", or "Serum". Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["COLLECTION"]["TISSUE_CELL_IDENTIFICATION"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: An empty value or a null value was detected in ["COLLECTION"]["TISSUE_CELL_QUANTITY_TAKEN"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The required property, "FLOW_GRADIENT", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "FLOW_RATE", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "COLUMN_TEMPERATURE", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "SOLVENT_A", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "SOLVENT_B", in ["CHROMATOGRAPHY"] is missing.
Warning: The "Moverz Quant" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "moverz_quant". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Warning: The "PubChem CID" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "pubchem_id". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Warning: The "Retention Index" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Warning: The column "Retention Index" was found in the ["MS_METABOLITE_DATA"]["Metabolites"] table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found.
