Issue Log:
Error: The value, "−2 V", for the subsection, "CAPILLARY_VOLTAGE", in the "MS" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required.
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.
Error: Unknown or invalid section, "FACTORS".
Warning: The "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 "Ion species" column at position 2 in the METABOLITES table, matches a standard column name, "ion". 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 "Ion species" column at position 2 in the METABOLITES table, matches a standard column name, "ion", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
