has_metric_category single value ID based metric median of TIC values in the RT range in which the middle half of quantification data points are identified MS The metric informs about the dynamic range of the acquisition along the chromatographic separation. MS:4000158 Median of TIC values in the RT range in which half of quantification data points are identified (RT values of Q1 to Q3 of identifications). These data points may be for example XIC profiles, isotopic pattern areas, or reporter ions (see MS:1001805). The used type should be noted in the metadata or analysis methods section of the recording file for the respective run. In case of multiple acceptance criteria (FDR) available in proteomics, PSM-level FDR should be used for better comparability.
