OMERO Reader (5.2)

OmeroConnector-Node extension for KNIME Workbench version 0.11.0.v202006260943

This (experimental) reader uses OMEREO.insight to access images from OMERO databases. In the configuration phase the insight viewer is used as graphical interface to select image IDs from the database. During the node execution the images are loaded from the database and get converted into an appropriate ImgLib format.
