A few cellprofiler and cellprofiler analyst questions

Few questions:

  1. In cellprofiler analyst, how can I change the property “channels_per_image”? Would this allow a different channel to be used for a thumbnail in CPA?
  2. In cellprofiler, is there a way to adjust the gamma for images that are saved with the saveimages module? I know you can adjust the gamma when viewing in cellprofiler, but im having trouble adjusting it so they save at the adjusted gamma?
  3. In cellprofiler analyst, is there a way to highlight which object is being selected in the thumbnail in the classifier? Additionally, is each thumbnail in the classifier centered on the object that was selected?
  4. In cellprofiler, how does filter by parent work? I’m getting many objects who have no parent when I filter by parent.
