Issue Log:
Error: An empty value or a null value was detected in ["PROJECT"]["PHONE"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["STUDY"]["PHONE"]. A legitimate value should be provided for this required key.
Error: The value, "40-50", 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: An empty value or a null value was detected in ["COLLECTION"]["COLLECTION_SUMMARY"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["TREATMENT"]["TREATMENT_SUMMARY"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["SAMPLEPREP"]["SAMPLEPREP_SUMMARY"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["MS"]["INSTRUMENT_NAME"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["MS"]["INSTRUMENT_TYPE"]. A legitimate value should be provided for this required key.
Error: The value, "-", in ["MS"]["ION_MODE"] should be one of "Positive", "Negative", "Positive, Negative", or "Unspecified". Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["MS"]["MS_COMMENTS"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["CHROMATOGRAPHY_TYPE"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["INSTRUMENT_NAME"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["COLUMN_NAME"]. A legitimate value should be provided for this required key.
Error: The required property, "FLOW_GRADIENT", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "FLOW_RATE", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "COLUMN_TEMPERATURE", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "SOLVENT_A", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "SOLVENT_B", in ["CHROMATOGRAPHY"] is missing.
Warning: The "ri" column at position 3 in the ["MS_METABOLITE_DATA"]["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 "ri_type" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index_type". 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 standard column, "other_id", was found in the METABOLITES table as "other_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 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "ri" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "ri_type" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "inchi_key" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "other_id" column at position 8 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "other_id_type" column at position 9 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
