Hi Steve!
Thanks for the answers.

Quoting Steve Smith <[log in to unmask]>:

I can open FA data in FSLveiw 2D nicely, but I cannot open any  FA-data (produced in FSL3 on Cygwin) in FSLview 3D. That means: It  atually works but I just don't see anything! Is that normal?

Have you tried setting the FSLView display range to 0:1?

Yes exactly. But I dont see anything. Acutally in the terminal it tells me:

"ERROR: In /home/duncan/VTK/Graphics/vtkPolyDataNormals.cxx, line 94
vtkPolyDataNormals (0xa2fccb8): No data to generate normals for!"

Are you talking about 3D view or all views? Can you see your FA data in 2D view? 

There is no specific mode for showing FA data in 3D. 3D view will do a surface for the main image - threshold it with the box at the top of the display. It will also: blend in stats images and show an iso-surface for them; show the surface of mask images. If you want to view DTI data then perhaps you could try thresholding it appropriately (i.e., to isolate regions of similar FA) then setting it to Mask/Label in the image info dialog then switch to 3D.

Is that a compatibility problem of FSL 3 and FSL 4?

Thanks again, cheers,
Markus
