# Slot: query 


_BIDS entity filter that selects one per-subject file under the experiment's ``dataset.bids_root`` when ``source`` is dataset-sourced (``dataset.subject.<measure>``). The active subject fills the ``sub-`` entity at resolution time; the remaining entities (e.g. ``desc: FCavg, atlas: Schaefer1000, suffix: relmat``) disambiguate among the subject's several networks/measurements. The same filter enumerates the cohort for the per-subject workflow fan-out, so one declaration drives both discovery and resolution._
