Issue Log:
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["FLOW_GRADIENT"]. A legitimate value should be provided for this required key.
Error: The value 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: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_A"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["CHROMATOGRAPHY"]["SOLVENT_B"]. A legitimate value should be provided for this required key.
Warning: The "NIST Theo. Mol. Mass" column at position 4 in the ["MS_METABOLITE_DATA"]["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 "NIST Lib Hit Formula" column at position 3 in the ["MS_METABOLITE_DATA"]["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 "NIST Lib Hit Formula" column at position 3 in the ["MS_METABOLITE_DATA"]["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:
2         C14 H37 N O Si3
6        C13 H33 N O2 Si3
7        C17 H37 N O3 Si2
8        C14 H35 N O2 Si3
10    C20 H35 F3 N2 O Si3
14       C18 H35 N O3 Si3
22       C11 H29 N O2 Si3
25       C14 H33 N O4 Si3
29       C11 H27 N O2 Si2
35        C17 H35 N O Si3
Warning: The "Pubchem CID" column at position 5 in the ["MS_METABOLITE_DATA"]["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 2 in the ["MS_METABOLITE_DATA"]["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.
