Hi David,

Looks like there is only one timepoint in the data-set. You need a sequence of timepoints when using gift.

There are multiple ways to enter the data. If you select "no" to question, "Is your data stored in one group directory?", you can specify number of subjects and sessions. You can check the manual for more info.

Thanks,
Srinivas

Subject: Errors for constrained ICA

Dear Experts,

Thanks very much for the excellent tool.

I am trying to perform constrained ICA (either Constrained ICA (Spatial)  or MOO-ICAR ) in our rsfMRI data (54 subjects with one session per subject) using GroupICAT v4.0c.

I had two kinds of errors as below:

1. When applying “Spatial Reference Based ICA”

After generating the mask, I had the following errors:

Error using icatb_read_batch_file (line 420)

Select Number of IC to be more than or equal to 2.

Error in icatb_setup_analysis (line 13)

        varargout{1} = icatb_read_batch_file(inputFile);

Error in icatb_batch_file_run (line 60)

    param_file = icatb_setup_analysis(inputFiles{nFile});

Error in setup_reference_ica>generateBatch (line 722)

icatb_batch_file_run(batchFileName);

Error in setup_reference_ica>done_Callback (line 422)

generateBatch(handles);

Error in gui_mainfcn (line 95)

        feval(varargin{:});

Error in setup_reference_ica (line 42)

    gui_mainfcn(gui_State, varargin{:});

Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)setup_reference_ica('done_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback.

2. When applying "Standard ICA/IVA", I have different problems as could not adequately include the subjects.

(1) When I keep each subject's data in one subject folder within the root data folder, after loading the data, I have the following errors

Error using icatb_setup_analysis>set_data_para (line 384)
Please re-select the data as the no of selected files is found to be 1 (F:\002_DAT-FC-SCH\010_GIFT\Data\Smoothed_2\Subject001\srniftiNORMS_Subject001_Session001.nii,1)

Error in ==> set_data_para at 384                                                                                                                                                                                                                                                                                                                                                                                             Error in ==> dataCallback at 947

Similar problems occurred when I select each subject's data manually.

(2) When I put all subjects' data within the root data folder (no subject folder), It seems ok that I can do the constrained ICA (no errors related to the number of IC).
However, only one subject was included in the analysis, not the whole 54 subjects.

I wonder what will be possible ways to deal with these problems?

The  Preprocessing steps for my data included preprocessing by fmriprep with default settings + denoising with default settings of the CONN toolbox + resampled to 3x3x3  & smoothing by SPM12.

Thanks very much for the help.

Best,
KC
