Issue Log:
Error: An empty value or a null value was detected for the subsection, "ADDRESS", in the "PROJECT" section. 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 "PROJECT" section. A legitimate value should be provided for this required subsection.
Error: An empty value or a null value was detected for the subsection, "ADDRESS", 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, "PHONE", in the "STUDY" section. A legitimate value should be provided for this required subsection.
Error: The value, "6- to 8-week-old", for the subsection, "AGE_OR_AGE_RANGE", in the "SUBJECT" section 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: The value, "0.450.5 mL/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 value, "1 L, splitless", for the subsection, "SAMPLE_INJECTION", in the "CHROMATOGRAPHY" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
Error: The value, "10 L", for the subsection, "SAMPLE_SYRINGE_SIZE", in the "CHROMATOGRAPHY" section should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. 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.
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: The "ri" column at position 3 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 "ri_type" column at position 4 in the 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 METABOLITES table has all null values.
Warning: The "ri" column at position 3 in the METABOLITES table has all null values.
Warning: The "ri_type" column at position 4 in the METABOLITES table has all null values.
Warning: The "inchi_key" column at position 6 in the METABOLITES table has all null values.
Warning: The "kegg_id" column at position 7 in the METABOLITES table has all null values.
