Define ROIs for each subject

Submitted by aliasaei on

I was wondering if we can define the ROIs for each subject individually in the original structural image space, instead of defining an ROI in the normalized space?

Thanks,
Ali

In "Define ROI":

1. Click + Seed Series

2. Choose a configuration file, e.g., Config.txt

The contents should be:

Seed_Time_Course_List:

/XX/MaskSub1.nii

/XX/MaskSub2.nii

/XX/MaskSub3.nii

 

 

Please make sure the first line is: "Seed_Time_Course_List:".

Thank you for the quick response. We have more than one mask files for each subject and would like to find the correlation between these ROIs.
For example for subject1 we have:
   subject1_mask1.nii
   subject1_mask2.nii
which both are in the t1mpragesag.nii space.
How should be the contests of Config.txt file in that case?

Thanks,
Ali

I also tested as you mentioned for just one ROI per subject and I get this error:

Error using DPARSFA_run (line 3893)
Name-value pair arguments must come in pairs.

Error in DPARSFA>pushbuttonRun_Callback (line 1761)
    [Error]=DPARSFA_run(handles.Cfg);

Error in DPARSFA (line 30)
    gui_mainfcn(gui_State, varargin{:});

 
Error while evaluating UIControl Callback

1. If you have several masks for a subject. I suggest you write a code to call y_SCA.

[FCBrain, Header] = y_SCA(AllVolume, ROIDef, OutputName, MaskData, IsMultipleLabel, IsNeedDetrend, Band, TR, TemporalMask, ScrubbingMethod, ScrubbingTiming, Header, CUTNUMBER)

2. What version of DPARSF/DPABI are you using for this error?

Hi Ali,
Then you can use y_ExtractROISignal.m

Seems like the output of the Y_SCA is a functional connectivity map for each ROI but we are looking for the correlation matrices.
We are using release V2.0_151201.
