Frequently Asked Questions (FAQ)

Submitted by YAN Chao-Gan on Fri, 11/02/2012 - 03:02
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.
 
Best,
 
Chao-Gan
 
1. What are the toolboxes needed for DPABI/DPARSF?
A: DPABI/DPARSF works well with MATLAB and Statistics Toolbox, Image Processing Toolbox and Signal Processing Toolbox. In addition, Parallel Computing Toolbox is needed if the users want to process multiple subjects in parallel computing mode.
 
2. How to solve the problem of “out of memory”?
A: Please refer to http://rfmri.org/OutOfMemory
 
3. What’s the ROI information of the templates provided in DPARSF?
 
4. Why the data after nuisance regression looks so strange (distorted)?
 
5. How to compare a single case with a group of controls?
 
6. Does the part "Reorienting T1 Image Interactively for XXX" require any input from the user?
 
7. What’s the input for smoothness estimation?
 
8. What’s the option of “IsTwoTailed” in GRF correction?

9. How to convert from voxel index to MNI coordinates and vice versa?
A: Please refer to http://www.rfmri.org/node/1300
 
10. Why linear trend should be removed before filtering?
A: Please refer to http://www.rfmri.org/node/1515
 
11. Why "calling other os commands from MATLAB" choke the processing, e.g., dcm2nii?
A: Please refer to http://www.rfmri.org/comment/2979#comment-2979

老师您好：

我是在做TFCE矫正的过程中出现了以下的报错，

错误使用 palm_takeargs (line 1133)

Unknown option: "Z:\data\rest\Hippocampus_FC\dpabi_analysis\349r\TFCE\Temp\Design.csv"

出错 palm_core (line 33)

[opts,plm] = palm_takeargs(varargin{:});

出错 palm (line 81)

palm_core(varargin{:});

出错 y_GroupAnalysis_PermutationTest_Image (line 102)

palm([TempDir,filesep,'PALMConfig.txt']);

出错 y_Correlation_Image (line 74)

    y_GroupAnalysis_PermutationTest_Image(DependentVolume,Regressors,OutputName,MaskFile,CovariateVolume,Contrast,'T',0,Header,PALMSettings);

    出错 DPABI_STAT_TOOL>ComputeButton_Callback (line 536)

        y_Correlation_Image(S, SeedSeries, OutputName, MaskFile, ImageCell, TextCell, PALMSettings);

出错 gui_mainfcn (line 95)

        feval(varargin{:});

出错 DPABI_STAT_TOOL (line 42)

    gui_mainfcn(gui_State, varargin{:});

出错 @(hObject,eventdata)DPABI_STAT_TOOL('ComputeButton_Callback',hObject,eventdata,guidata(hObject))

我的DPABI版本是3.1，matlab2014a，想请教一下这种报错一般是什么原因，需要怎么处理？谢谢您的回复。

严老师您好，我做了三组数据的ANCOVA，然后用hsd做多重校正，得到的三组之间的对比，其中G1VSG2 G1VSG3，两个结果不能在VIEWER中显示，但是G2VSG3却可以正常显示，报错信息如下：

错误使用 repmat
复制因子必须为整数行矢量或整数标量。
 
出错 y_AdjustColorMap (line 74)
    NewColorMap(Begin:End,:) = repmat(OriginalColorMap(iColor,:),[Segment 1]);
 
出错 w_OverlayList>RedrawOverlay (line 1354)
ColorMap = y_AdjustColorMap(ColorMap,...
 
出错 w_OverlayList>Accept_Callback (line 1423)
            OverlayHeader=RedrawOverlay(OverlayHeader, handles.MainFig);
 
出错 gui_mainfcn (line 95)
        feval(varargin{:});
 
出错 w_OverlayList (line 42)
    gui_mainfcn(gui_State, varargin{:});
 
出错 @(hObject,eventdata)w_OverlayList('Accept_Callback',hObject,eventdata,guidata(hObject))
 
 
错误使用 waitfor
Error while evaluating UIControl Callback
请问这是什么原因，要怎么解决？
谢谢！

结果值里面有NaN？还是全0？

Nmin还有Pmin是0，Nmax有数值，colorbar值是12.

是看这个么？

两组不能加载的Pmax是inf，能加载的那组是数值，是因为这个缘故么？

YAN Chao-Gan

那是因为有Inf值的出现。仔细思考一下你的图像为什么会出现Inf值。

数据整理、预处理都是按照严老师的视频来操作的，还请严老师指教。谢谢！

通常可能是你的数据有些问题，想办法查找一下。

可能是那两组设置有问题，结果文件为空。

严老师您好：

         关于repeated measures ANCOVA在dpabi软件统计模块的使用中和ANCOVA有什么区别吗？例如只有一组病人治疗前后两个时间点的数据可以用repeated measures ANCOVA吗？我在使用这个模块时将两个时间点影像数据放进去可以出结果，但它这个和配对t检验有什么区别吗？

           感谢老师

只有两个时间点用配对t检验。如果有3个时间点，用repeated measures ANCOVA。
