has_column has_metric_category base peak intensity table ID free metric single run based metric multiple spectra based metric base peak intensity maxima per time ranges The maximum base peak intensity (MS:1000505) of all spectra in a single run in the given retention time ranges. The time windows are specified by the 2nd column defining the start time in seconds and the 3rd column defining the duration in seconds. To define a range from a starting time until the run's end, -1 may be used for the duration with 0 for the start. MS:4000203 MS Duration second
