Issue Log:
Error: An empty value or a null value was detected in ["PROJECT"]["PROJECT_SUMMARY"]. A legitimate value should be provided for this required key.
Error: The value, "Embryo", 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: The value, "N2", in ["MS"]["COLLISION_GAS"] should be one of "Nitrogen" or "Argon". Ignore this when more complicated descriptions are required.
Error: The value, "Neb - 10 L/min, Sheath 9 L/min", in ["MS"]["DRY_GAS_FLOW"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['L/hr', 'L/min']. Ignore this when more complicated descriptions are required.
Error: The value, "Neb/Sheath - 350C", in ["MS"]["DRY_GAS_TEMP"] 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 value, "35 PSI", in ["MS"]["GAS_PRESSURE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['psi', 'psig', 'bar', 'kPa']. 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, "40", in ["CHROMATOGRAPHY"]["COLUMN_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']. Ignore this when more complicated descriptions are required.
Error: The value, "300 Bar (Max)", in ["CHROMATOGRAPHY"]["COLUMN_PRESSURE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['psi', 'bar']. Ignore this when more complicated descriptions are required.
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 column pair, "other_id" and "other_id_type", in the METABOLITES table should have data in the same rows, but at least one row has data in one column and nothing in the other.
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 "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 "ri_type" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
