Error information about two sample t-test of dynamic ALFF

Submitted by zuolonglotu@gm… on Fri, 06/07/2019 - 09:08

Dear Prof. Yan,

When I did two sample t-test of dynamic ALFF, the error information showed as follows,

Reading images from "F:\exp\ALFF_sub_10001.nii" etc.

Assignment has more non-singleton rhs dimensions than non-singleton

subscripts

Error in y_ReadAll (line 109)

Data(:,:,:,j) = single(DataTemp);

Error in y_TTest2_Image (line 40)

[AllVolume,VoxelSize,theImgFileList, Header] = y_ReadAll(DependentDirs{i});

Error in DPABI_STAT_TOOL>ComputeButton_Callback (line 531)

y_TTest2_Image(S, OutputName, MaskFile, ImageCell, TextCell, PALMSettings);

Error in gui_mainfcn (line 96)

feval(varargin{:});

Error in DPABI_STAT_TOOL (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)DPABI_STAT_TOOL('ComputeButton_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback

Thanks a lot！

You should use CV or STD other than the 4D dynamic indices for t-tests.

Dear Prof. Yan,

1. Is CV means Concordance Value? The voxel or volume-wise concordance can be obtained in the TemporalDynamics fold. Is that the right understanding?

2. Is STD means Standard Deviation? I cannot find the values in the TemporalDynamics fold. How can I get the STD?

Thanks a lot！

CV is coefficient of variance.

STD is standard deviation.

They are in the temporaldynamicsmetrics directory other than the temporaldynamics4d directory.
