Resting-state fMRI topics

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:

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 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.

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.

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);

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。

Threshold in the viewer

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

dparsf自动把所有时间点存成4D文件

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

Names of ROIs

 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.
