Question about the GLM

Submitted by Feng on Fri, 10/09/2020 - 03:25

Hi, I have a few questions about the general linear modeling (GLM) and statistical analysis by using DPARSF.

1. Which step or button of the GUI with Template Parameters perform the GLM? Do we need to perform GLM in resting state fMRI data?

2. If we do, how can we visualize the results of significant regions?

3. This question is about the loading of Subject name with text file. So I made the text file as the figure shown below. But each time I loaded this text file, the GUI only showed one subject instead five of them. Is there any specific format of text file we need to make?  Some errors were shown below (highlighted by yellow):

Operands to the || and && operators
must be convertible to logical scalar
values.
 
Error in DPARSFA>UpdateDisplay (line
1984)
if (theOldIndex>0) &&
        (theOldIndex<= theCount)
 
Error in DPARSFA>LoadSubIDFromTextFile
(line 478)
            UpdateDisplay(handles);
 
Error in gui_mainfcn (line 95)
        feval(varargin{:});
 
Error in DPARSFA (line 30)
    gui_mainfcn(gui_State,
    varargin{:});
 
Error while evaluating uimenu Callback
 

Very appreciated if you could give any indication! Thanks!

Best,

Feng

No, GLM is not for resting-state fMRI analysis.
