[Insight-users] 3D Resampling

[Karthik Krishnan]

Hi Kevin

I would first check if you can read your Analyze file. (There have been 
reports in the past of certain Analyze files not being read in correctly).
Use InsightApplications/ImageViewer to open your Analyze file and check 
if you see what you expect to see.
