Issue Log:
Error: The value, "Not applicable", 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: 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: The required property, "ANALYSIS_TYPE", in the "ANALYSIS" section  is missing.
Error: The value, "800", for the subsection, "SPECTROMETER_FREQUENCY", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['MHz']. Ignore this when more complicated descriptions are required.
Error: The value, "2", for the subsection, "LINE_BROADENING", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['Hz']. Ignore this when more complicated descriptions are required.
Error: The value, "na", for the subsection, "BINNED_INCREMENT", in the "NM" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['ppm']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected for the subsection, "BINNED_DATA_PROTOCOL_FILE", in the "NM" 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, "BINNED_DATA_EXCLUDED_RANGE", in the "NM" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: Unknown or invalid section, "FACTORS".
Warning: The "database match" column at position 2 in the METABOLITES table, matches a standard column name, "other_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 column "database match" was found in the METABOLITES table, but this column implies that another column, "other_id_type", should also exist, and that column was not found.
Warning: The standard column, "other_id", was found in the METABOLITES table as "database match". If this column contains database IDs for standard databases such as KEGG, PubChem, HMDB, etc., it is recommended to make individual columns for these and not lump them together into a less descriptive "other_id" column.
