I frequently face a problem with the 'Labeling to RGB Img' and the workflow interrupts with the message below.
ERROR ValueToCellNodeModel Error in row Row0: -146
ERROR Labeling to RGB Img Execute failed: java.lang.ArrayIndexOutOfBoundsException: -146
I also attached a copy of corresponding entry from the Knime.log file.
The strange thing is that it is not happening everytime even when using the very same dataset. Also when the workflow stops I can simply restart/execute the node and it continues without any problem.
What I do prior to this node is to run a CCA, then Labeling Filter, and then I normalize the image I want to use as background in the 'Labeling to RGB Img'. I do this for two different channels in parallel branches of the workflow. There are usually between 500-2000 labels.
I am using Knime 2.10 and KNIME Image Processing 18.104.22.168407091732. Happens on Win7 and Win 2012 R2.
Any idea what could lead to this behaviour/error?
Thanks in advance,
