About Masks in REST have different origin coordinate with SPM images

Submitted by mwst on Wed, 08/04/2010 - 11:43

老师：
     你好，我使用rest提供的mask来提取全脑、CSF、白质的信号，但是我发现这些mask的中心点坐标即origin coordinate是0，而SPM里面的图像则不是。所以无论使用MRIcro的overlay还是SPM的checkreg功能，rest提供的mask与SPM里面的图像都不配，这样的话是否提取mask内的信号是可靠有效的呢？因为我不知道其计算的原理，所以在此发问，我的图像都已经是重采样后与mask相同的体素大小和坐标框。
   请老师解释一下。
