老师好，我用REST做了双样本t检验后，用REST slice Viewer显示，然而我看到自由度上面默认的是33，然而我的两组被试一共37，也就是自由度应该是n1+n2-2=35，我记得严老师说过REST slice Viewer可以读取自由度，这是不是REST slice Viewer的错误吗？

老师您好，用REST可以计算被试一个感兴趣区域和全脑各体素之间的功能连接，请问如果我想计算全脑每个体素和其他体素之前的相关系数，如何用REST实现呢？谢谢

严老师，您好，我看到有些文章做功能连接的相关分析时是用点与点的功能连接与量表的相关，我想请教一下，我如果做点和全脑的相关图可以和量表做相关可以吗，如果可以的话，该怎么解释呢，谢谢严老师了，突然意识的这个问题，有点急，期待您的火速回复，呵呵，谢谢啦。。。。。

用REST做相关分析用AlphaSim校正,报告结果里的Peak intensity代表r值吗？

请教一下严老师，使用DPARSFA里new segment+DARTEL处理了一下数据，有一些疑惑，想请严老师指导一下：
1.SPM8自带的VBM8分析是不是默认的使用DARTEL的方法？

2.我分别使用SPM8自带的VBM8和DPARSFA的new segment+DARTEL的方法对同一批（2组）数据跑出来的结果进行了比较，发现结果差别很大，用DPARSFA里new segment+DARTEL的方法跑出来的结果比VBM8发现了更多的灰质体积减小的区域，尤其是在双侧边缘系统（请见图），这就恰好和之前的文献报道很一致了，而使用VBM8跑出来毫无这些结果，请问DARTEL比传统的VBM方法要更敏感和准确一些吗？
