Issue Log:
Error: The value, "Normal/Overweight/Obese", for the subsection, "WEIGHT_OR_WEIGHT_RANGE", in the "SUBJECT" section should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['g', 'mg', 'kg', 'lbs']. Ignore this when more complicated descriptions are required.
Error: The value, "Male/Female", for the subsection, "GENDER", in the "SUBJECT" section should be one of "Male", "Female", "Male, Female", "Hermaphrodite", or "N/A". Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected for the subsection, "MS_COMMENTS", in the "MS" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: The value, "1ml/min", 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, "12.8psi", for the subsection, "COLUMN_PRESSURE", 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: ['psi', 'bar']. Ignore this when more complicated descriptions are required.
Error: The value, "250C", for the subsection, "INJECTION_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'] or "room temperature". Ignore this when more complicated descriptions are required.
Error: The required property, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section  is missing.
Error: The required property, "SOLVENT_A", in the "CHROMATOGRAPHY" section  is missing.
Error: The required property, "SOLVENT_B", in the "CHROMATOGRAPHY" section  is missing.
Warning: There are duplicate samples in the MS_METABOLITE_DATA section.
Warning: The "quantified m/z" column at position 3 in the 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 ID" column at position 4 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 "KEGG ID" column at position 5 in the 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.
Warning: The "retention index" column at position 2 in the 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 METABOLITES table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found.
Warning: The "PubChem ID" column at position 4 in the METABOLITES table has all null values.
Warning: The "KEGG ID" column at position 5 in the METABOLITES table has all null values.
