oc_mindensity — mindensity (1D density minimum)
What it does: Finds a cutoff at a local minimum in the 1D density, typically separating negative vs positive peaks.
oc_tailgate — tailgate (1D tail cutoff)
What it does: Places a threshold at a distribution tail to remove debris/low-signal or isolate high-signal tail.
oc_quantile — quantile (1D percentile)
What it does: Gates by percentile (e.g., top 5% brightest), making thresholds more comparable across samples.
oc_flowClust2d — flowClust (2D mixture)
What it does: Fits a 2D mixture model and gates by modelled clusters in XY space.
oc_kmeans — kmeans (2D clusters)
What it does: Clusters points in 2D using k-means and gates one or more clusters.
oc_trapezoid — trapezoid (2D polygon)
What it does: Creates a trapezoid-shaped polygon gate, typically for scatter clean-up (e.g., FSC/SSC style regions).
