Hi Bahram
Yes, as Lisa said, Tensor-iCA is not the right thing for this, we
recommend using tempiral concatenation and ICA instead. If you then
want to test for between group differences it seems best for you to
wait until we have released the dual regression approach which now is
being beta-tested for release sometime later in August (hopefully).
FSLview will read melodic_IC files as 4D files, you can use the (i)
button to select a color map etc and browse the different components
using the volume selector. SImilar to feat outputs, freesurfer should
be be OK with thresh_ztstatX as inputs (the thresholded maps that you
get saved when you select the 'output full stats folder'). Or simply
split the 4d file melodic_IC into separate 3d volumes and use these in
freesurfer
