Issue Log:
Error: An empty value or a null value was detected in ["PROJECT"]["FUNDING_SOURCE"]. 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 ["PROJECT"]["PROJECT_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 ["STUDY"]["STUDY_COMMENTS"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "18", 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_DURATION"]. 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 ["COLLECTION"]["ADDITIVES"]. 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 ["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"]["EXTRACT_ENRICHMENT"]. 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 ["SAMPLEPREP"]["EXTRACT_CLEANUP"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "-70 eV", in ["MS"]["FRAGMENT_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V']. Ignore this when more complicated descriptions are required.
Error: The value, "1 ml/min", in ["MS"]["HELIUM_FLOW"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['mL/min']. Ignore this when more complicated descriptions are required.
Error: The value, "250", in ["MS"]["ION_SOURCE_TEMPERATURE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. 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: The value, "1 ml/min", in ["CHROMATOGRAPHY"]["FLOW_RATE"] 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, "250", in ["CHROMATOGRAPHY"]["INJECTION_TEMPERATURE"] 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'] or "room temperature". Ignore this when more complicated descriptions are required.
Error: The value, "250", in ["CHROMATOGRAPHY"]["TRANSFERLINE_TEMPERATURE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required.
Error: The required property, "FLOW_GRADIENT", 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 "quantified m/z" column at position 3 in the ["MS_METABOLITE_DATA"]["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 "PubChem ID" column at position 4 in the ["MS_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 "KEGG ID" column at position 5 in the ["MS_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 "HMDB" column at position 9 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "hmdb_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 "METLIN" column at position 11 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "metlin_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 "ChEBI" column at position 10 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "chebi_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 ["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 column "retention index" was found in the ["MS_METABOLITE_DATA"]["Metabolites"] table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found.
Warning: The "retention index" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "quantified m/z" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
