用DPARSF 做到Normalize报错

报错都是：

  * - SPM8: spm_affreg  ----------------------------------------------

        There is not enough overlap in the images
        to obtain a solution.
        
        Please check that your header information is OK.
        The Check Reg utility will show you the initial
        alignment between the images, which must be
        within about 4cm and about 15 degrees in order
        for SPM to find the optimal solution.

        ----------------------------------------- 

这种现象不是每个人都有,一开始只是偶然现象，昨天做的有两个人都是这样，应该不是扫描参数的问题吧, 并不是个个有错啊.

是什么原因呢,在网上查了有两个人报了这种错误, 后来都说解决了,但都没说是如何解决的, 急啊！！

我也试了在realign后,用realign生成的mean文件与结构像配准，coregistor(Estimate) 里Source image用的是mean文件，Reference image用的是结构像文件，再做Normalize,但是也不行。急！！！
