![]() ![]() This particularly impacts random sampling of objects with the classifier and graphing tools. We’ve made more general improvements to database interactions to minimise the number of SQL calls which are made.Handling of custom SQL filters has been optimised.Scoring should now be much faster: In one of our testing datasets, scoring 50,000 objects with a RandomForest classifier completed in ~20 seconds,compared to over 10 minutes in CellProfiler Analyst 2. The “ Score Image” and “ Score All” functions within the classifier have been revised to run more efficiently.The “Create Filter” dialog now includes a “Test” button so that filters can be validated before saving them.Īnother area of focus has been the performance of different aspects of CellProfiler Analyst.This should prevent CellProfiler Analyst from freezing when the user tries to adjust display settings with multiple tiles already loaded. The image size/contrast control panel now only updates the display when the slider stops moving.A “ fit to window” button is now available in the image viewer.Sometimes this is useful for reinforcing training, but users have often requested the ability to suppress these duplicates. Randomly sampling objects can return the same object multiple times. You can now optionally prevent duplicate objects in the Classifier by using the “Advanced” menu and remove existing duplicates with the right-click menu within each bin.pressing “1” will move any selected tiles from the “Unclassified” bin into the first class that you defined, thus enabling rapid classification using only the keyboard. Within the classifier, you can now use the arrow keys and number keys to select tiles and move them into class bins.Within the classifier, you can now drag to select multiple tiles at once. ![]()
