Issue Log:
Error: An empty value or a null value was detected for the subsection, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: The value, "NA", for the subsection, "FLOW_RATE", in the "CHROMATOGRAPHY" section 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", for the subsection, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section 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 for the subsection, "SOLVENT_A", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "SOLVENT_B", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: Unknown or invalid section, "FACTORS".
Warning: The "PubChem ID" column at position 2 in the 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 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 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 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 table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
