Hi,

I am using Slicer 4.10.1.  
Whenever I try to run Brainfit General registration for Rigid registration, I always get this error:

Error: user can only specify one output transform type

However, I only selected Slicer Linear Transform as the output Type. Why does this occur?

The program will only work if I set an Output Image Volume but No Linear/BSpline Transform.

Solved the issue. It was because I never clicked on “reset to default” after I performed a registration beforehand.
