subjects not listed

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？

AlphaSim rmm 参数设置

老师您好，

关于AlphaSim的使用，我有几个问题，您能否帮助我一下？谢谢

1. 我现在不是resting-state fMRI，可否用rest包里的AlphaSim?
2. 我的voxel size是4x4x5，我rmm应该设置成多大呢？
3. 我在处理fMRI图像的时候，用了8x8x8的平滑，我直接设置FWHM为8可以吗？还是说一定要用估计的FWHM？

非常感激!

最近用DPARSF老出错，从slice timing就开始，但是单独做slice time又没事，现在我把slice timing后的又重新做，跑了一会儿又报错，请严老师看看怎么回事，如下：
Failed 'Realign: Estimate & Reslice'
Error using ==> spm_bsplinc
File too small.
