Issue Log:
Error: An empty value or a null value was detected for the subsection, "NUM_MALES", in the "STUDY" 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, "NUM_FEMALES", in the "STUDY" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: The value, "40 Celsius", for the subsection, "COLUMN_TEMPERATURE", 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: ['°C', 'C']. Ignore this when more complicated descriptions are required.
Warning: The "Mass Accuracy Score" column at position 3 in the METABOLITES table, matches a standard column name, "mass". 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 "Molecular Weight" column at position 9 in the METABOLITES table, matches a standard column name, "mass". 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 "Molecular Formula" column at position 8 in the METABOLITES table, matches a standard column name, "formula". 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 "Molecular Formula" column at position 8 in the METABOLITES table, matches a standard column name, "formula", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:
