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, "MS_COMMENTS", in the "MS" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: The value, "350ul/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 required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section is missing. Error: The required property, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section is missing. Warning: The "Moverz Quant" 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 "mass spectrum" column at position 7 in the METABOLITES table, matches a standard column name, "mass_spectrum". 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 5 in the 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 "KEGG ID" column at position 6 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 "Local ID" column at position 4 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 "Retention Index" column at position 2 in the METABOLITES table, matches a standard column name, "retention_index". 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 column "Retention Index" was found in the METABOLITES table, but this column implies that another column, "retention_index_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: The "Moverz Quant" column at position 3 in the METABOLITES table has all null values. Warning: The "Local ID" column at position 4 in the METABOLITES table has all null values. Warning: The "KEGG ID" column at position 6 in the METABOLITES table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
