    • Interactive thresholds setting on the channel histogram
    • Analysis history that you can save, to reproduce the analysis with the same dataset or reuse with other datasets. This also facilitates batch analysis.
    • Undo mechanism, to quickly revert for example an unfortunate object deletion or filtering.
    • Import analysis and visualization conditions from any other open O.A. instance, so that you can replicate them for different datasets.
    • Render all objects with their accompanying numerical label, for easier analysis reference.
    • Reference 3D cube to know the orientation of the dataset even at large zooms.
    • Cropped datasets can be exported as new channels to the original image, not only overwriting the original ones.
    • Optional on-screen tips to guide you.
    • More possibilities for setting the ROI.
    • More possibilities for selecting anchors, also by filtering the objects based on the reported parameters.
    • Discarded objects and selected anchors are remembered, for the current segmentation parameters, when changing frames in a time series or channels in a pipe.
  • Improvements in the SFP renderer:
    • The appearance of the SFP table is now configurable (on/off/mirror).
    • Increased tilt range to 180 degrees, i.e. view from underneath the table.
    • SFP animations are more fluent.
