Re: Displaying .mat files

Hello,

I see that you are running the 0.4.0 release. Are you running window as well? Is the error message truncated?

Did you download and install ImageJ?

http://www.vtk.org/Wiki/ITK_Release_4/SimpleITK/GettingStarted#Recommended_Software

There also is a bug in that binary release where on windows it may not find the ImageJ executable. The work around is to install ImageJ into C:\ImageJ, and then add that path the the executable into your PATH environmental variable. Alternatively you could compile a more recent version from the source.

We debated if we should release a patched version for this fix, but decided that we should continue out effort on development instead of packaging, and since it was only called a beta release its not unexpected to have a couple small bug. But if people clamor too much a couple patched versions could be made.

Hi Bradley

 

Have you ever tried to test the 'SimpleGaussian.py' example? how can I test it?

 

I'm interested in test this example, I think it has sitk methods that can help me to understand the tool. I'm new in ITK and I'm trying with SimpleITK first.

Hello,

I am not sure that ITK can directly read all .mat images. There is the HDF5 image IO that may work for a subset, but I have never tried this combination my self.

If you are using SimpleITK with Python, you may look for mat image reader in another python package such as scipy. They should be able to export the image to a numpy array, then this can be imported into SimpleITK with the sitk.CreateimageFromArray() method.

By default SimpleITK uses ImageJ to display images from the sitk.Show method. More information about getting this setup can be found here:
