Issue Log:
Error: The value, "nine-month-old", in ["SUBJECT"]["AGE_OR_AGE_RANGE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['weeks', 'days', 'months', 'years']. Ignore this when more complicated descriptions are required.
Error: The required property, "ANALYSIS_TYPE", in ["ANALYSIS"] is missing.
Error: The required property, "filename", in ["NM"]["NMR_RESULTS_FILE"] is missing.
Warning: The "PubChem CID" column at position 4 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "pubchem_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 "PubChem CID" column at position 4 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "pubchem_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    8988 145742
Warning: The "KEGG ID" column at position 3 in the ["NMR_METABOLITE_DATA"]["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 "Database Match" column at position 2 in the ["NMR_METABOLITE_DATA"]["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 ["NMR_METABOLITE_DATA"]["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.
