single subject paired t test error

Hi everyone!

I'm trying to run a single subject rsfmri analysis. I run DPARSF and get my 2 zFC maps , one for each of the 2 sessions (pre and post treatment). The maps look good in the viewer! I put these 2 zFC maps in the stat analysis tool by selecting a paired t test modality, in order to to get a comparison-t-map between the two. Is this right so far? The stat analysis tool look running fine and provide me with a map. However, this map cannot be seen in the viewer. When trying to upload it, matlab provides me with the following error:

Error using repmat
Replication factors must be a row vector of integers or integer scalars.
Error in y_AdjustColorMap (line 74)
    NewColorMap(Begin:End,:) = repmat(OriginalColorMap(iColor,:),[Segment 1]);
Error in w_OverlayList>RedrawOverlay (line 1354)
ColorMap = y_AdjustColorMap(ColorMap,...
Error in w_OverlayList>Accept_Callback (line 1423)
            OverlayHeader=RedrawOverlay(OverlayHeader, handles.MainFig);
Error in gui_mainfcn (line 95)
Error in w_OverlayList (line 42)
    gui_mainfcn(gui_State, varargin{:});
Error in>@(hObject,eventdata)w_OverlayList('Accept_Callback',hObject,eventdata,guidata(hObject)) 
Error using uiwait (line 81)
Error while evaluating UIControl Callback
When I upload the same map on fslview, it doesn't show up, meaning all voxels have zero intensity.
Do you have any idea about how to fix this or alternative ways to run a simple single-subject pair t test?
Thank you so much for your help!!!


You can not run paired t test on only one subject.

Ok, I thought you could do it if you had repeated measures.

thank you!

You need to have multiple subjects.
