how to get a negtive correlated network with the seeds of ROI using REST?

i have seen the course online about how to use the REST for FC,but how to get a negitive correlated network?must be different with the positive FC .i want to know the accurate steps.thanks  

如何提取图像中体素的ReHo ALFF

 大家好:

严老师,辛苦了。请教您一个问题

 严老师,
您好!
我是首都医科大学宣武医院的研究生。我现在在做帕金森病认知障碍的脑功能连接的研究。用的是您的DPARSF来处理数据。
我的第一批数据按您的教程顺利做完了。但是第二批数据则老出错。我尝试了重新装软件等,但总是有这样那样的问题,但我都看不懂。
最多的错误如下:

Removing the linear trend: E:

DPARSFA error when stopping and restarting pipeline

DPARSFA has no problem processing a NIFTI dataset through the steps of Slice Timing and Realign. However, I get a reproducible error if I try to separate the steps in the pipeline. For example:

1) Processing the NIFTI dataset through Slice Timing alone works fine.

关于Alphasim的问题

老师:
      您好。我用VBM比较两组被试灰质差异,想用Alphasim进行校正。标准化后得到的图像voxel size为1*1*1。我有以下几个问题:

     1、在用REST Alphasim计算时,mask应该用全脑的还是用灰质的?

各位老师好,请问一个关于提取全脑时间序列的问题。

我目前正在进行的课题需要分别提取全脑每个VOXEL的时间序列。我已使用dparsf完成原始数据的预处理,接下来应该怎么操作呢?
我在论坛中看到有人提到可以使用rest_to4d这个函数,
我在MATLAB中输入 rest_to4d(‘J:\Analysis\FunImg\sub1‘)
报错如下:
Read 3D EPI functional images: "J:\Analysis\FunImg\sub1"........................................??? Error using ==> rest_spm_slice_vol
File too small.

发现了一个可能的与matlab2012a函数输出不一致的问题的问题

各位好:

我用matlab2012a跑数据,没到slicetiming,结果报错。
Error using fileparts
Too many output arguments.

Error in cfg_util>local_initapps (line 1144)
[p n e v] = fileparts(appcfgs{k});

Error in cfg_util (line 518)
local_initapps;

Error in cfg_util (line 401)
cfg_util('initcfg');

Error in spm_jobman (line 206)
cjob = cfg_util('initjob', mljob);

Error in DPARSF_run (line 326)
spm_jobman('run',jobs{1});

Error in DPARSF>pushbuttonRun_Callback (line 938)
[Error]=DPARSF_run(handles.Cfg);

Error in gui_mainfcn (line 96)
feval(varargin{:});

Error in DPARSF (line 40)
gui_mainfcn(gui_State, varargin{:});

Error while evaluating uicontrol Callback
然后我查了下2012a的fileparts函数,发现只有三个输出[pathstr, name, ext] = fileparts(filename) ,但是我之前用的2009、2010、2011版本的matlab却会有四个输出,[pathstr, name, ext,versn] 。

希望我们的software多向上兼容下新的matlab版本。

order of regression and filtering

IS it possible to change the order of steps so that the regression of nuisance variables is done prior to the filter or simultaneous as in AFNI 3D BP? DO you think this is helpful?

Frequently Asked Questions (FAQ)

Hi all,
 
Besides the information provided in the Courses, there were still lots of questions about resting-state fMRI data processing. Here we'd like to build a FAQ section for your convenience. However, the FAQ is just started and will be developed gradually.
 

mICA提取成分

老师好,请问用mICA提取10个RSNs的时候只能根据以前文献中报道的脑区筛选吗?有没有其他方法啊。谢谢
