batch mode with heatmap

Hi all,


Like I postet in the Image Processing Forum I have some problems with the KNIME batch mode.

Forum =

workflow =

Images for the Image Reader =


One of the problems is that the heatmap node doesn’t work.

Have any one some ideas for solutions please ?


Kind regards,


Hi Flo,

I've never used the batch mode so far but I managed to take your workflow, reset the heatmap node, select an appropriate path to save the image to and run it in batch mode.

./Knime -nosplash -application org.knime.product.KNIME_BATCH_APPLICATION -workflowDir="/......../workspaces/ws_2.9/open issues/workflow_batch/"
INFO 	 main BatchExecutor	 ===== Executing workflow /........../workspaces/ws_2.9/open issues/workflow_batch =====
2014-05-08 13:45:21.355 Knime[61785:903] Process manager already initialized -- can't fully enable headless mode.
INFO 	 main BatchExecutor	 Workflow execution done Finished in 3 secs (3659ms)
INFO 	 main BatchExecutor	 ============= Workflow executed sucessfully ===============

I checked the destination location and the image has been saved. It seems everything worked.

So I don't know what's going wrong in your case or if I did something different to what you did. Do you have any error-messages or anything one can use to troubleshoot a bit more?

That is so weird. I don't get any error messeges it just doens't execute but I'll have to give it some more trying. At least I know I'm doing something wrong :D


Thanks a lot,


Sorry, that I cannot help.

Which operating sytem are you on and which KNIME version do you use?

Win 7 SP1 64-bit and KNIME 2.9.2

Do you reset the workflow with the -reset command or do you "just" start it ?
