well, obviously you can't directly compare the slices that the latter subject is missing. A simple solution is to just get rid of the 4 slices to make the dims equal.

Dear FSL experts:

I have two questions about FSL group analysis:

If volume sizes (function image) of subjects within one group are different (for example, one subject is  64x64x35 and another subject is 64x64x31), how FSL processes those datasets?

Whether FEAT (GLM) and MELODIC (ICA) process different size of volumes in the same way or not?

Thank you very much.
