Issue Log:
Error: The value, "2 days after birth", for the subsection, "AGE_OR_AGE_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: ['weeks', 'days', 'months', 'years']. Ignore this when more complicated descriptions are required.
Error: The value, "above 1.3Kg at birth", 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: An empty value or a null value was detected for the subsection, "ADDITIVES", in the "COLLECTION" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: An empty value or a null value was detected for the subsection, "SAMPLE_DERIVATIZATION", in the "SAMPLEPREP" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: An empty value or a null value was detected for the subsection, "SAMPLE_SPIKING", in the "SAMPLEPREP" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: An empty value or a null value was detected for the subsection, "COLUMN_NAME", in the "CHROMATOGRAPHY" section. A legitimate value should be provided for this required subsection.
Error: The required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section  is missing.
Error: The required property, "FLOW_RATE", in the "CHROMATOGRAPHY" section  is missing.
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: The "PubChem" column at position 3 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" column at position 4 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 "HMDB" column at position 2 in the METABOLITES table, matches a standard column name, "hmdb_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 4 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
