Issue Log:
Error: An empty value or a null value was detected in ["TREATMENT"]["CELL_MEDIA_LASTCHANGED"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "200 µL/min", in ["CHROMATOGRAPHY"]["FLOW_RATE"] 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, "40", 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: The value, "5 µL", in ["CHROMATOGRAPHY"]["SAMPLE_INJECTION"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
Warning: The "quantitated m/z" column at position 4 in the ["MS_METABOLITE_DATA"]["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 3 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 "KEGG ID" column at position 2 in the ["MS_METABOLITE_DATA"]["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 "retention index (minutes)" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index". 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 column "retention index (minutes)" was found in the ["MS_METABOLITE_DATA"]["Metabolites"] table, but this column implies that another column, "retention_index_type", should also exist, and that column was not found.
Warning: The "Controlinvitro_1" column at position 2 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "Controlinvitro_2" column at position 3 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "Controlinvitro_3" column at position 4 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "DRB18invitro_1" column at position 11 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "DRB18invitro_2" column at position 12 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
Warning: The "DRB18invitro_3" column at position 13 in the ["MS_METABOLITE_DATA"]["Data"] table may have incorrect values. 90% or more of the values are the same, but 10% or less are different.
