您好，老师！
我在预处理时点了Automask这个选项，但是生成的mask是一些不规则的多边形，后面在生成group mask时也是如此。
我想问这样会不会影响到后面预处理的准确性？
这样的group mask应该不适合在统计比较中使用吧？那么我可以用一个先验的brain mask作为统计比较的mask吗？
期待您的回复！祝您万事胜意！

各位老师好，我采用dpabi的quality control对被试进行筛选，在采用90%的group mask进行了阈值为mean+2*SD的coverage threshold后，几乎把所有的被试都筛除了，请问这是怎么回事呢？？

Hi Dr. Yan,
I performed ALFF, fALFF, ReHo and DC by DPARSFA, starting from the directory FunImgARCW.
The input data of TR was 4 seconds by mistake, while the correct one should be 3 seconds.
My question is whether this incorrect input of TR would affect the final caculation.
Thank you in advance and best regards.
Chen

Hi. Eeveryone.
1. I was confused by the starting directory while preprocessing ReHo. Should we start from FunImgARCW and check the "Filter" upon the option of "Normalize by DARTEL " as shown in the ReHo.png.?
