It sounds like an openGL rendering issue. If you run glxgears command, do you see a blank window or spinning 3D gears?

There was an issue with my description. I meant to refer to volume data. Freeview is displaying a black view, even though it loads the images. Unfortunately, nothing is visible.

I have a number of problems. Freeview opens fine but when I load a column in it just shows a black view. Have you ever encountered this problem? I'm so confused about using the tool for registration. Can I do registration between MRI and PET modalities of the same subject using "bbregister"?
