老师好，我使用dpabisurf处理demo数据的时候报错。
After GRF correction, significant clusters are larger
Forums
老师好！
我在对一张R.nii图像进行GRF矫正之后，发现看到的cluster比没做矫正之前更大了，这是不是不合理啊？
我的操作是这样的：
1）在Dpabi View的overlay里选定一张R.nii 图像 （这个界面的Nmax 和Nmin分别代表什么呢？我在两台不同电脑上打开同一个图，它出现的数字是不一样的）
2）在Overlay configure 输入P（0.05），df=5（sample size =7。 这里有点奇怪，df改为5后，accept了，但是重新点开‘df’，又是原来默认的数字，得改两遍才会变成我想要的那个数字。）
完成这一步之后，看到的cluster都很小很小，应该是过不了GRF矫正了？
3）Cluster里那一栏选GRF，选定我自己的mask--- voxel p value （0.0214）----cluster p value（0.05）---- Two tailed----Compute
这一步之后，激活的团块面积就变大了！
请求老师解答！非常谢谢！！

Dear community
I hope this email finds you well
I would kindly ask if it is possible to use DPABI on a data which has been preprocessed using FSL?
The data we will use is a resting fMRI data and we would like to do ALFF/fALFF and ReHo analyses on this data..
I would be very end thankful if you can help.
Best Regards
Farzin

严超赣老师：
您好！
我在对数据进行预处理时，选用的顺序是ARCFW。有几个问题：
1、请问将配准放在最后一步，会产生其他的噪声影响吗？
2、是否有文章是按照这个顺序进行预处理的呢？
3、是否需要改为ARWDCF的顺序？
4、如果不更改顺序时遇到审稿人提问，该如何回复更合适呢？
谢谢！

Hi, prof. Yan.
I have several questions about dpabisurf preprocessing.
I performed dpabisurf preprocessing for 10 subjects(PreAcuS001-S010).
At first, I thought it was going well, but an error occurred and dpabisurf stopped working(attached photo).
Perhaps the problem occurred during the process of fmriprep.
And It seems that an error occurred during the segmentation of one subject(S008).

严老师好，各位老师好，这里请教一个文件，我是否可以通过dpabi把多个不同脑区的mask合并成1个多值mask呢？如果可以，我应该如何操作呢？期待能得到你们的指导
How to add atlas in DPABI_VIEW?

I am trying to locate the position of some brain structures in DPABI_VIEW with the atlas provided.
However, existing atlas can only show rough structures while I want the position of some fine structures.
I tried to find some atlas on the internet whose file format are ".nii", but DPABI_VIEW needs both ".nii" file and ".mat" file to successfully add an atlas.
I wonder how I can succefully add an atlas to DPABI_VIEW and if there is any recommended website for me to easily find suitable atlas and corresponding “.mat" file.
