Issue Log:
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 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 "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 "CompositeSpectrum" column at position 10 in the METABOLITES table, matches a standard column name, "composite_mass_spectrum". 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 "Compound Name" column at position 13 in the METABOLITES table, matches a standard column name, "name". 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 "HMP ID" column at position 14 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 "LMP ID" column at position 16 in the METABOLITES table, matches a standard column name, "lm_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 "CAS Number" column at position 8 in the METABOLITES table, matches a standard column name, "cas_number". 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 "ChEBI ID" column at position 9 in the METABOLITES table, matches a standard column name, "chebi_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 "Ionization mode" column at position 15 in the METABOLITES table, matches a standard column name, "ionization_mode". 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 "quantified m/z" column at position 3 in the METABOLITES table has all null values.
Warning: The "PubChem ID" column at position 4 in the METABOLITES table has all null values.

Warning: The "ChEBI ID" column at position 9 in the METABOLITES table has all null values.
Warning: The "Ionization mode" column at position 15 in the METABOLITES table has all null values.
Warning: The "KEGG ID" column at position 5 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "CAS Number" column at position 8 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "HMP ID" column at position 14 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
