[Insight-users] ImportError: No module named ITKMetricsv4Python

[Bradley Lowekamp]

Hello Mathieu,

I unfortunately can't help you with your WrapITK issue. But expanding VectorImage support for SimpleITK was in my agenda for this week.

I would like to know more about this error. It is generated when you have a VectorImage and try to get a numpy array?

Also how did you read in your image?

Did you try using the VectorIndexSelctionCast function to select a component of the VectorImage? Then convert it numpy?

I very much would like know the features that are missing in SimpleITK to better support VectorImages for 4D image processing.

Thanks,
Brad

Did you compile WrapITK your self? Did you try running out of the build directories? Perhaps there is some step missing in the current installation.
