Issue Log:
Error: An empty value or a null value was detected for the subsection, "ADDRESS", in the "PROJECT" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "PHONE", in the "STUDY" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "COLLECTION_SUMMARY", in the "COLLECTION" section. A legitimate value should be provided for this required subsection.
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: An empty value or a null value was detected for the subsection, "SAMPLEPREP_SUMMARY", in the "SAMPLEPREP" section. A legitimate value should be provided for this required subsection.
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: There are duplicate samples in the MS_METABOLITE_DATA section.
Error: The following metabolites in the, MS_METABOLITE_DATA table were not found in the METABOLITES table:
	"Factors"
Warning: The "KEGG_ID" 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:
40    BOCASN
Warning: The "Local_ID" 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 "Local_ID" 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 "Local_ID". 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.
Warning: There is a metabolite name, "Factors", in the METABOLITE_DATA table that is probably wrong. It is close to a header name and is likely due to a badly constructed Tab file.
Error: The MS_METABOLITE_DATA table does not have a column for "Samples". It is likely misspelled or using a common incorrect substitute.
