各位老师您好：
我基于某几个ROI计算ALFF，每个被试得出一个*.nii文件，然后我做one-sample t-test，得出T*.nii文件，我该如何取出我定义的ROI的ALFF值呢？弱弱的问一下，ALFF可以用来做些什么工作呢？我之前这样做的步骤对吗？
谢谢各位老师帮忙回答！
DPARSFA计算出的resault下 REHO 有三种类型的文件sw*** swm*** swz*** 三种类型打头的文件
zMap是减均值除标准差，mMAP则是除均值,是这样子理解的吗？ 那是用哪个进行统计分析呢？谢谢老师了
Hi,
We have fMRI data from different sites with different parameters. I have preprogressed them separately using dparsfa. And then can I put them together as a group to analyse the functional connectivity?
Thanks.

Hi,
I have a question about how to decide ICA component number. I am to tell my riviewer that it is based on the experience (1/3-1/4 volumes, is it right?), but I did not find the relevant references. Could you provide some references for me? thanks. And any suggestion about how to answer this reviewer's question is appreciated.
Hi, Yan,
I created a specific T1 template. Can I use this template in VBM8_toolbox analysis (default setting, except the change of template during normalization). It will be right?
By using REST, can I merge one gray matter map and one white matter map into a united .nii image (like template 1 in the VBM_toolbox).
Dear experts,
I have a couple of questions regarding the 'T1 dicom to Nifti' function as well as the reorient boxes which are marked with an asterisk in the DPARSFA toolbox. It would be very helpful if you had any comments or details on the following issues:
大家好，我是rest的初学者，病组和对照作双样本T检验，添加.txt的协变量，其内的数据应该如何输，一个数一空格，还是一个数一回车，两种方法试着均报错
Two Sapmle T Test Calculating...
.......Error using horzcat
Dimensions of matrices being concatenated are not consistent.
对了，还有，如果我想用多个指标作协变量，这多个指标的数按顺序放在一个.txt里吗？
