[Insight-users] ITK to VTK for 4D images

[Bradley Lowekamp]

Hello,

What is the current issue you are having with your SimpleITK implementation?

Currently, I am aware what we don't have support to convert VectorImage to numpy arrays. But that is near the top of my todo list this week. 

Also, I am interested in your input data? What do you mean by 4D? 3D + time? 3D+ multichannel? What is your input file format and what is the meta data that is report? If there is an issue with SimpleITK reading it, I'd like to see a sample file to see if support could easily be added.
