mask出错了，能怎么改正么

各位老师们好！

最近处理的一批数据，其中有些被试是头部上下颠倒的，于是用fsl翻转过来并在fslview里看着正常后，后用DEPARSFA处理。结果是，那些头部曾经颠倒了的被试result都为空，而其他没有颠倒的被试都挺正常的，看PicturesForChkNormalization也是那些颠倒的被试normalize没配齐。

我的处理步骤是，slice timing, realign, coregister, Newsegment+DARTEL, Nuisance covaraite regression (poly trend 1, Fiston 24, Global signal, WM signal, CSF signal), Warp Masks into individual space, ALFF/ReHo等，normalize， smooth。 本来想贴图上来的，可能是网速慢贴不上，只好这么简单描述了。

然后我就逐个文件去检查，发现到FunImgARCF看着都正常，头部颠倒的和没有颠倒的被试都差不多，T1ImgNewSegment 灰白质分割也是正常的，但Masks 和Results里都是空的。

有关使用rest计算degree centrality结果输出的问题

严老师您好，我做了30个正常儿童中心度，在rest计算DC的界面有两个输出结果分别是output directory for weighted sum和output directory for binarize sum（如下图），请问我要用这两个输出文件分别是什么意思，我要下一步进行统计计算用哪个文件夹。
下面是我分别用binarize和weighted进行单样本T检验的结果，感觉稍微有些不一样，请严老师指导，谢谢。

With DPARSF basic edition, everything works fine, but when I use the DPARSF advanced edition the subjects are not listed, although each has the dicoms in a folder with the subject code in the FunRaw Folder in the Working Direktory, that is correctly set (like before). Does anybody know why the DPARSF toolbox does not recognize the subject folders!?

Thanks a lot!

mask与统计学分析

最近做组间统计的时候遇到一个问题，我用rest image calculator把三组单样本显著的区域做了并集，然后在这个mask内做两组间的对比，我发现有点问题，回头查看mask内有1、2、3值，应该是对应于三组，将这一mask1、2、3全部统一为1后，结果不一样了，论坛老师们是否可以帮忙分析一下？
