Hello there ,
You can certainly miss the registration for Lev1 analysis by simply opening GUI and shutting off initial structural image, main structural image and standard space tabs under the Registration tabs. That way registration will not happen. However the bigger trick is Lev2 analysis where you are combining multiple feat (to do the fixed effect analysis) that belong to the same task. But here also what you can do is: You can create an indentity matrix (4x4) for example_func2standard.mat and also create standard.nii.gz which is nothing but MNI152_T1_2mm.nii.gz (template). Make sure you create this under reg directory of each feat (that is you have to create directory reg, since you shut it off during Lev1). Than run updatefeatreg on the reg directory and see yourself what will be created.
So this is a way around it, but I hope the template for your data is registered in MNI space.

Subject: [FSL] How to skip registration
Hi FSL members,
Is there a way to skip the registration in FEAT? My data is already registered. Anyway, even if the data is registered and the registration is done, should I get really bad alignment between the template and the image (as shown in the registation page of the report)? Thanks in advance,
Ibi
