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.
 
Best,

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。

看不出来是什么原因。可以试试别的电脑,或者别的数据。

谢谢严老师的指导!

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?
