In this webinar, we will explore the new features and functionalities in HALO, HALO AI, and HALO Link 4.2 designed to enhance performance, streamline workflows, and expand analytical capabilities. In HALO 4.2, new annotation tools such as a multi-select feature and improved annotation management, including batch annotation import and rename, boost efficiency. Also, object data is moved out from the database into optimized parquet files, significantly improving load times and overall system performance. 

HALO AI 4.2 offers channel-invariant pretrained models that streamline nuclear and cell segmentation by leveraging all fluorescent channels, and multiple membrane markers can now be selected when further training the pretrained membrane segmentation model. Version 4.2 also brings an updated AI annotation tool that is smaller, faster, and optimized for pathology data, delivering a smoother annotation experience. Users now have greater control over model training with adjustable hyperparameters, including learning rates and class weights. 

In version 4.2, HALO Link now supports viewing Z-stacks on brightfield images. The latest version also introduces a Diagnostic Monitor add-on to help administrators troubleshoot performance issues with image loading. For those looking for additional ergonomics options, integration with the 3D Connexion SpaceMouse is now available. Finally, both HALO and HALO Link 4.2 support the use of third-party AI apps, enabling models developed by users outside of HALO or by external vendors to be launched and viewed within the platforms.
