Issue Log:
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, "NA", 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, "NA", 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.
Warning: The "PubChem ID" 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 "pal1_1" column at position 11 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "pal1_2" column at position 12 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "pal1_3" column at position 13 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "gpps_1" column at position 20 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
