Issue Log:
Error: The value, "55", 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.
Warning: The "exactmass" 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 "super_class" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "class". 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 "main_class" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "class". 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 "sub_class" column at position 7 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "class". 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 "210628_LW_Magauer_1-14_48h_LM_PBMC_n1-4_sample_25" column at position 26 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "210628_LW_Magauer_1-14_48h_LM_PBMC_n1-4_sample_26" column at position 27 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "210628_LW_Magauer_1-14_48h_LM_PBMC_n1-4_sample_65" column at position 66 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "210628_LW_Magauer_1-14_48h_LM_PBMC_n1-4_sample_80" column at position 81 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
