Hi there @MANOUBI,

welcome to KNIME Community Forum!

Well don’t know French but seems it is reporting that something is not a valid 32-bit application. What system are you running and have you chosen appropriate KNIME version?

Hi there @MANOUBI,

i see you marked my answer as solution. Glad it helped but does this mean other problem is resolved as well. If not someone else will have to jump in as not into Image Processing…

Hi @ipazin
when i execute ilastik node I got this error, Ilastik output file does not exist,

`Can’t read image in Ilastik Headless Node at RowId: testclaire.tiff : java.nio.file.InvalidPathException: Ilastik output file does not exist:

C:\Users\ua\AppData\Local\Temp/ilastik/0141f312-d314-49c2-a943-e01adfedce10/file0_result.tiff''`

Hi there @MANOUBI,

just wondering have you made any progress with Ilastik? Heard it can be a bit tricky but personally never tried it so unfortunately can’t help. If not will ask someone to jump in.

Hi @ipazin,
I find solution for this problem by working with one channel image, for trainning image in ilastik and for image in knime ( by adding splitter node ).
But, the problem now that ilastik don’t save export setting “Simple segmentation” it’s by default “Probability” .
Working with “Probability” export setting for segmentation need to add a splitter for the colormap and also need thresholding probability image. the result is not prescis and threasholding add a sort of noise even if the threashold value is 0.98 .
I wonder if there is an other solution ?

Thank you,
MANOUBI
