for SPM authors: Apparently SPM/MatLab 4.x can't handle long directory names for reading data files in under the REALIGNMENT command. If you have not caught this for SPM99, can you try to get the fix in? I am able to read these files once I change the length of the overall (in characters) directory path. I am guessing that it breaks somewhere around 100 characters for the directory path. -- Robert C.
