I would check to insure epi and T1 image are both oriented the same as MNI template, in addition to checking that the orientation information in the headers are correct.
Good luck.

> I am a very beginner of FSL. When I use FEAT to analyse the first level analysis, I always get an "empty brain map". Actually this happened for several times. I really do not know what is wrong. Here is how I did the analysis:
>
> 1. extract the brain form the T1-contrast structure images;
> 2. I followed the FSL manual to set the FEAT parameter. I believed I set the TR and martrix design file correctly.
> 3. In the registration tab, I register the image to both the T1-contrast structure brain which I get in the first step and the standarn space (MNI 152 T1 brain image).

> What's more, I also get the zero cluster list in a higher level analysis.
