Issue Log:
Error: The value, "230°C", for the subsection, "ION_SOURCE_TEMPERATURE", in the "MS" section 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 for the subsection, "MS_COMMENTS", in the "MS" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: The value, "250°C", for the subsection, "INJECTION_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'] or "room temperature". Ignore this when more complicated descriptions are required.
Error: The value, "290°C", for the subsection, "TRANSFERLINE_TEMPERATURE", in the "CHROMATOGRAPHY" section 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 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 "quantified m/z" column at position 3 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 4 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 "KEGG ID" column at position 5 in the 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 "rtimes (min)" column at position 2 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.
