Dear Siawoosh,
in my version of SPM there is a defaults setting for realignment called
"lkp" which flags the realignment parameters that are allowed to change. I
am not sure whether this is in standard SPM, too. If not, then you would
have to modify the spm_realign.m code and set lkp to zero for the
parameters you want to fix at zero.
