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: An empty value or a null value was detected for the subsection, "CHROMATOGRAPHY_SUMMARY", in the "CHROMATOGRAPHY" 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. Warning: The "PubChem CID" column at position 2 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 "Local ID" column at position 3 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. Error: The section, METABOLOMICS WORKBENCH, has a sub-section, DATATRACK_ID, that is duplicated.
