Issue Log:
Error: The value, "000000", for "PROJECT_ID" in the file header must be the letters "PR" followed by 6 numbers. Ex. "PR001405".
Error: The value, "Male and 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: The value, "once", for the subsection, "TREATMENT_DOSEDURATION", in the "TREATMENT" section should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['h', 'weeks', 'days']. Ignore this when more complicated descriptions are required.
Error: The value, "300ul/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, "40", 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.
Error: The value, "20min", for the subsection, "ANALYTICAL_TIME", 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: ['min']. Ignore this when more complicated descriptions are required.
Error: The required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section  is missing.
Warning: The "Molecular Weight" column at position 5 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 "InChIKey" column at position 4 in the METABOLITES table, matches a standard column name, "inchi_key". 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 "InChIKey" column at position 4 in the METABOLITES table, matches a standard column name, "inchi_key", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
0    1
1    2
Warning: The "KEGG" column at position 3 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 "KEGG" column at position 3 in the METABOLITES table, matches a standard column name, "kegg_id", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
0    1

Warning: The "Human Metabolome Database" 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 "Human Metabolome Database" column at position 2 in the METABOLITES table, matches a standard column name, "hmdb_id", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
