咨询一个Slice viewer和Xjview相同P值下T值不一样的情况

老师您好：
请教一个在Slice viewer和Xjview中相同P值下T值不一样的情况：
我的数据是结构像数据，数据是1.5 X 1.5 X 1.5的，分析被试的灰质体积和问卷得分的相关，方法是在SPM中进行多元回归分析，得到的spmT_0001使用Xjview打开，设置p value=0.005，此时的T=2.8784，然后我使用Slice Viewer打开spmT_0001文件，设置p=0.005，此时的T=3.1966。两个软件输入相同的p值对应的T值不一致，不知道是什么原因。

DPARSF outputs/results for second level analyses

Submitted by tsheng75 on Sat, 01/05/2013 - 08:02

 Hi guys,

I am a relatively new user of DPARSF/A and I am wondering which output/results files are the most appropriate to feed into second level group analyses? For example, does one use the 'ALFFmap', 'mALFFmap', or 'zALFFmap' files from each individual subject for a group-level t-test or regression? Some of the online documentation (albeit for previous versions of DPARSF) seem to suggest using the 'm' or 'z' files, but is that appropriate? In task-based fMRI, the con* images are fed into second level (and they are neither mean-normed nor z-scored). Please advise, thanks!
