严老师：
您好！

学生有一个问题请教一下老师，我目前想使用REST计算偏相关分析，但是我在rest界面上没有找到相应的功能按键。例如，假设我目前有ROI1,ROI2,ROI3，我想看一下基于voxel水平的whole-brain的FC，但是会把ROI3的影响去掉。所以我的作法是提取ROI3的时间序列，然后使用REST，进行FC计算，但是把ROI3的时间序列放在txt文档中，作为
covariable，不知道我的作法是否合适，还请老师帮忙解答一下。
谢谢！

Hi,Yan.I am using demo data to learining DPARSF. But When I step to Reorient, error is occuring

Hi, I am a fershman in using dpabi. Now, I am running the demo data from dpabi website. Here, I meet a question adout scling timing, which wants to get your reply.
1. If I start to preprocessing from dcm data, the step of slice timing error is:

Error using DPARSFA_run>(parfor body) (line 571)

Index exceeds matrix dimensions.

Error in DPARSFA_run (line 546)

parfor i=1:AutoDataProcessParameter.SubjectNum

Error in DPARSFA>pushbuttonRun_Callback (line 1761)

[Error]=DPARSFA_run(handles.Cfg);

Error in gui_mainfcn (line 95)

Dear sir,

I have been trying to generate random networks but it always comes up with
an error posted below.
Can you kindly suggest how to rectify it.I have tried adding to matlab path
also removing other graphvar files.

Thanks and regards

Hi!
I am currently having difficulty when I ask GraphVar to calculate
smallworldness using random networks. It seems to run well until the final
step of exporting the variables; then, I get the following error:

Index exceeds matrix dimensions.

Error in GraphVar_CalcExport_Callback (line 66)
if(sum(size(Result{1}) > 1))

Error in gui_mainfcn (line 95)

Hello,

I was not able to find the "dynamic" windows in the most recent version
of GraphVar 6.02.
Have i missed anything?

Thanks.

Dear Dr Yan,

I am trying to run ICC for my resting state images, but would like some more information about how best to do this.

Can it be used on raw images or just con images? If it can be used on raw images can you tell me the best way to input them. I tried a 4D nifti file - it ran but it gave a very odd image.

Apologies if there is a guide, I can't seem to find one.

Many Thanks

Sarah

Hello sir,

I am trying my best to calculate graph metrics in graphvar using MATLAB2015a .I have changed my variables like subject ids as s1,s2,etc.also the male female varibles used is(0/1).

But still I am getting this error.Please help me fixing it soon.
