Hi,

If you already have these 3D images, one per subject, you can use randomise to run your test.  See the randomise help page for details.  You'll need to use fslmerge to create a single 4D image first and this will serve as your input into randomise.

Cheers,
Jeanette

Dear FSL experts,

I have exported from MATLAB some 3-D images (with extension something.hdr) and now I want to use FSL to perform group statistical tests.

In more detail I have 12,  3-D images, registered in the MNI space, each one corresponding to a different subject.
All I want now is to perform some statistical group tests in order to identify which areas are more activated within these 12 subjects.

Since my images are already registered, I want to avoid the registration registration and the pre-stats procedure in FEAT gui.

I would appreciate if anyone could help me on this.

Thanks,
Prokopis
