KNIME Pipeline. Image processing with the ImageBee plugin for KNIME. Movies are read in by the VWSReader node and corrected for animal movement with the Stabiliser node. The upper pipeline then follows the method described in this paper and computes a glomerular map that is displayed by the visualisation node ShowRoom. The lower pipeline normalises movies by subtracting the mean activity before odour stimulation (node FoldChange) and computes glomerular time series in matrix T given matrix S from the ConvexCone node (Algorithm 1) and the movie A. Time series are written to a CSV file. See main text for details on the individual processing steps.
