Operating system: Windows 7 professional
Slicer version: 4.6.2
Expected behavior: Sample data from tutorial should execute registration
Actual behavior: I downloaded the sample data set to perform registration of DTI to MRI from the Slicer page: Projects:RegistrationLibrary:RegLib C03 - NAMIC Wiki
However, I am able to successfully perform only part 1 of this two-step process. The program takes too long to compute resampling of the DTI volume, and then I get an error message as attached with this post. I tried doing the registration on 2 different computers, but the error persisted. How can I resolve this?
I was able to reproduce the issue. The problem is that due to some reason this CLI module uses .mat extension for writing transforms, which is not capable of handling composite transforms. I’ll change it to use .h5, as that can handle any combination of transforms. Tomorrow’s nightly version should work well.
