Issue Log:
Error: The value, "8 week, 20 weeks at end of treatment", for the subsection, "AGE_OR_AGE_RANGE", in the "SUBJECT" section 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 value, "450 µL/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°C", 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 "HMDB_ID" column at position 5 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:
79    n/a*
85    n/a*
86    n/a*
87    n/a*
88    n/a*
Warning: The "Study_Compound_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 "RT" column at position 4 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.
Warning: The column "Study_Compound_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 "Study_Compound_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: The "Chow_5_PVP" column at position 36 in the MS_METABOLITE_DATA table has all null values.
