Issue Log:
Error: An empty value or a null value was detected in ["SUBJECT"]["GENOTYPE_STRAIN"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "25 ± 2 °C", in ["TREATMENT"]["PLANT_TEMP"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["FLOW_GRADIENT"]. A legitimate value should be provided for this required key.
Error: The value, "1.2 mL/min (Helium)", in ["CHROMATOGRAPHY"]["FLOW_RATE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['mL/min', 'uL/min', 'μL/min']. Ignore this when more complicated descriptions are required.
Error: The value in ["CHROMATOGRAPHY"]["COLUMN_TEMPERATURE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_A"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_B"]. A legitimate value should be provided for this required key.
Error: The value, "250°C (splitless mode)", in ["CHROMATOGRAPHY"]["INJECTION_TEMPERATURE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C'] or "room temperature". Ignore this when more complicated descriptions are required.
Error: Unknown or invalid subsection, "SOLVENT_C", in ["CHROMATOGRAPHY"].
Warning: The "quant_mz" column at position 2 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 "Molecular weight (Da)" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "mass". 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 "CAS_ID" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "cas_number". 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.
