    Good Morning
    I´d like to represent VTA simultaneously for each patient in 3-dimensional view during Group Analysis.
    Is there any way to do it?
    Thanks to everybody for this amazing toolbox!

    Hi, yes, you can check “map variable to VTA” and just set the variable to a set of ones. Then press visualize 3D.
    At a later stage can add the result manually to a scene by choosing “add objects” > “add roi” in the 3D viewer. The sum of the VTA is stored in the lead group folder under /statvat_results.

    Best, Andy

    Hi Andy,
    Thank you so much for this useful answer.
    It seemed relatively easy, but I have tried in different way and I have obtained whenever the same error:
    Error using spm_vol>spm_vol_hdr (line 80)
    File “/home/***/Documents/DBS_dystonia/practice/pat_5/stimulations/gs_20180110144432/vat_right.nii” does not exist.

    Error in spm_vol (line 61)
    v = spm_vol_hdr(deblank(P(i,:)));

    Error in ea_load_nii (line 28)
    nii=spm_vol(fname);

    Error in ea_exportvatmapping (line 28)
    Vvatr=ea_load_nii([M.patient.list{pt},filesep,’stimulations’,filesep,’gs_’,M.guid,filesep,’vat_right.nii’]);

    Error in lead_group>vizbutton_Callback (line 417)
    ea_exportvatmapping(M,options,handles);

    Error in gui_mainfcn (line 95)
    feval(varargin{:});

    Error in lead_group (line 42)
    gui_mainfcn(gui_State, varargin{:});

    Error in
    matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)lead_group(‘vizbutton_Callback’,hObject,eventdata,guidata(hObject))
    Error while evaluating UIControl Callback.

    I don´t really know why it gives this error. I checked in the patient folder and that VTA is normally present.
    Thereafter It happens for each patients that the process considers as first.

    I´d be grateful if you could give an answer to the problem.
    Kind regards, Raf
