Issue Log:
Error: Unknown or invalid subsection, "ACQUISITION_DATE", in ["MS"].
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["INSTRUMENT_NAME"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["COLUMN_NAME"]. A legitimate value should be provided for this required key.
Error: The value, "1 mL min-1", 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, "50-275°C", 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: The value, "50°C ramped to 250°C by 12°C s-1", 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: The required property, "FLOW_GRADIENT", 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 "PubChem" column at position 2 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 "KEGG" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "kegg_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.
