SimpleITK::ERROR: Error in administrating child process: [No such file or directory]

Question

My Python Code is:

import SimpleITK as sitk
resultImage = sitk.Elastix(sitk.ReadImage("fixedImage.nii"), \
                       sitk.ReadImage("movingImage.nii"), \
                       "translation")
sitk.Show(resultImage, 'test', debugOn=True)

I get this error:

Traceback (most recent call last):

File "/home/faps/PycharmProjects/Rigid Registration/code.py", line 5, in <'module> sitk.Show(resultImage, 'test', debugOn=True)

File "/usr/local/lib/python2.7/dist-packages/SimpleITK-1.0.1rc1.dev333+gabf92-py2.7-linux-x86_64.egg/SimpleITK/SimpleITK.py", line 7741, in Show return _SimpleITK.Show(*args, **kwargs)

RuntimeError: Exception thrown in SimpleITK Show: /media/faps/ECF664A5F664722E/SimpleElastix/Code/IO/src/sitkShow.cxx:515: sitk::ERROR: Error in administrating child process: [No such file or directory]

I am working on Ubuntu 16.04 with Pycharm.

I have ImageJ in this address: /media/faps/ECF664A5F664722E

the line sitk.Show(... is cousing this error. Can somebody tell me what this error means and how I can solve it?

SimpleITK, by default, uses ImageJ to display images. It seems that cannot find ImageJ. The debugOn flag is supposed to make SimpleITK print out the search path it uses to find ImageJ, but I don't seat in your error message. — Dave Chen

As my comment said, SimpleITK can't seem to find ImageJ. On Linux systems, the search path includes the current working directory, ${HOME}/bin, /opt and /usr/local.

If your ImageJ executable is in another location, or if you want to use some other application to display images, you can use the SITK_SHOW_COMMAND environment variable.

More documentation about the Show function in the doxygen: https://itk.org/SimpleITKDoxygen100/html/namespaceitk_1_1simple.html#ac8416e6e7f02dedfe8373b83dbea411d
