Hi Sid,
Sorry for such a late reply!
Yes the V<i> files are in 4D format.
In order to extract the x,y,z components, you can use fslsplit.
For example:
> fslsplit outputs_V1 components
In which case the x,y,z components of V1 will be respectively:
components0000.nii.gz
components0001.nii.gz
components0002.nii.gz
Cheers,
Saad.
