Issue Log:
Error: The required property, "COLLECTION_SUMMARY", in the "COLLECTION" section  is missing.
Error: An empty value or a null value was detected for the subsection, "TREATMENT_SUMMARY", in the "TREATMENT" section. A legitimate value should be provided for this required subsection.
Error: The value, "0.25 ml/min; 0.4 ml/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, "35C", 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.
Warning: The "mz" 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 "neutral_mass" column at position 4 in the METABOLITES table, matches a standard column name, "mass". 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 "formula" column at position 2 in the METABOLITES table, matches a standard column name, "formula", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
1        C3 H7 N O2
3        C3 H7 N O3
5        C5 H9 N O2
7       C5 H11 N O2
9        C4 H9 N O3
10     C2 H7 N O3 S
12      C6 H13 N O2
13      C6 H13 N O2
14      C6 H13 N O2
17       C4 H7 N O4
23       C5 H9 N O4
24    C5 H11 N O2 S

56    C8 H16 N O9 P
Warning: The "refmet_name" column at position 5 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 "rt" column at position 6 in the METABOLITES table, matches a standard column name, "retention_time". 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.
