[ITK] [ITK-users] sitk::ERROR Unable to determine ImageIO Reader

[Bradley Lowekamp]

Hello,

This error message may need to be improved [1]. I think your file name does not exist.

Try assigning your filename string to a variable. This will enable inspection of the variable's value and checking os.path.isfile() to determine if it exists. You may want to look into using Python raw strings for windows paths [2]. I think that if you pass a filename to SimpleITK with forward slashes it should still work too. 

Also SimpleITK 0.9.0 is now out :)

HTH,
Brad

[2] https://docs.python.org/2/tutorial/introduction.html#strings

Also your filename string contains python escaped sequences. Using the Windows contentions of backslashes for filenames is very problematic.

It is worth noting that it is not a memory issue as I have used test images in the .tiff format and I still obtained the same errors. Furthermore, I am running SimpleITK in 64 bit python as I needed the extra memory in past projects I worked on. In order to test finally whether the issue originates from the code or from SimpleITK errors, I ran a set of old code (which I know worked) and it gave me the same error. I attached a screenshot of the error below. As you can (or cannot) see, I receive the error: sitk::ERROR: Unable to determine ImageIO reader for “C:\MIIA\Kim_Lab\Liver\test.tiff”.
