Hi, a similar message as disccused before get I when trying to run realign and unwarp (even with unpacked updates ...) Error message: Cell contents reference from a non-cell array object. In file "D:\Analysis_Software\SPM\spm8b\config\spm_run_realignunwarp.m" (v2312), function "spm_run_realignunwarp" at line 71. I guess '{1}' should be remove in line 71 and 72. At least it works in my case, since I don't have phase maps for that study.
