向老师请教一个关于VBM的问题

我使用DPARSF分割出了白质及灰质等结构,请问这样分割出来的数据需要用什么软件及进行什么样的步骤来统计

VBM数据录入

 
老师:
      您好!
      DPARSF V2.3中有VBM (New segment+DARTEL),我想利用这个来做vbm分析。我按软件的数据格式要求准备好了数据,因为我用的是nifti格式的数据,starting directory name也改成了T1Img,但是为什么我的数据load不进去呢?请问一下老师这个问题如何解决?
        谢谢老师!

      

deconvolved GCA

Dear Zang and REST experts
 
In July, I asked you a question about REST GCA when I was troubled in the case of y2x analysis.
Then, I had acquired reasonable outcomes and thank you for all your help.
 
And now, there are some discussions about deconvolved GCA.

ALFF

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?

ALFF

          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

Reorient function in DPARSFA

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:

VBM

 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).  

ICA

 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. 

rest-GCA数据结果请教

老师:
     您好!
     请原谅我的冒昧打扰。最近本人在做GCA的ROI-Wise网络研究,其中遇到了一些问题想向您请教。
     (1)order的设定是否与roi为二元或者多元有关吗?如果有,不知道具体的设定规则是什么样的?
     (2)在做基于残差的计算时,生成了多个文件,不知道每个文件中的数值分别代表什么?其值是Z分数还是F分数?(文件以附件形式添加)

FC parameter

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.

Jane
