Resting-state fMRI topics

 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:

Read 3D EPI functional images: "E:\Analysis\FunImgNormalizedSmoothed\PD27"..............................................

??? Error using ==> ctranspose

Out of memory. Type HELP MEMORY for your options.

Error in ==> rest_detrend at 40

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.

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.

Error in ==> rest_spm_read_vols at 34
 Y(:,:,p,i) = rest_spm_slice_vol(V(i),rest_spm_matrix([0 0 p]),V(i).dim(1:2),0);

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 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。

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?

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

Hi All,
I am a new user of this amazing REST toolbox. I have a question regarding the threshould on the viewer.
Why the range of the threshold is set differently for each subject? What does the P =1 under the threshold represents? And Technically, how can I save a cluster of activation e.g in the right hippocampus?

Thanks
Nahla

各位好：

我用最近版的dparsf和rest跑数据，自动把我的数据存成了4D文件，这样导致我做回归全脑信号、wm csf信号时出错。而且貌似waitbar不出现了。

能不能自动的将4D convert成3D+time points呢？

谢谢

 Dear all -
I extracted the connectivity matrix between all ROIs from the atlases provided with DPARSFA (AAL, Craddock, Dosenbach, ...). How do I find out the name of each ROI for each atlas? For the Harvard Oxford Atlas a file with anatomical labels is provided, but I'm not sure on how to use that.
