Issue Log:
Error: The value, "150 µL/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, "35°C", 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 "pos m/z" column at position 5 in the 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 "neg m/z" column at position 6 in the 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 2 in the 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 "RT, min" column at position 7 in the METABOLITES table, matches a standard column name, "retention_time". 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.
Error: The "polarity" column in the METABOLITES table indicates multiple polarities in a single analysis, and this should not be. A single mwTab file is supposed to be restricted to a single analysis. This means multiple MS runs under different settings should each be in their own file.
