CAT12 ROI error

Dear Neurostars community

I seem to have an error with the utilisation of the ROI option in the CAT12 toolbox and was wondering if you were able to provide any input.

I am running a VBM analysis using the CAT12 toolbox in SPM (latest version for both). I am using the default options (with TIV ANCOVA correction and multiple regression) based on the installation guide and I am using a Ubuntu 22.04 environment. After setting up the model and visualising the results I am trying to use the same SPM.mat file to run the ROI option. After selecting p value level, Neuromorphic atlas and Vgm I receive the error:

Unable to perform assignment because the left and right sides have a different number of elements. 

Error in cat_stat_analyze_ROIs (line 402)
  Pcorr{3}(defined_measure) = p_tissue;

Error in cat12>pushROIAnalysis_Callback (line 236)

Error in cat12>gui_mainfcn (line 1090)

Error in cat12 (line 118)
    gui_mainfcn(gui_State, varargin{:});

Error in cat12>@(hObject,eventdata)cat12('pushROIAnalysis_Callback',hObject,eventdata,guidata(hObject)) (line 710)
Error while evaluating UIControl Callback.

I have tried rerunning everything and this did not solve this issue.

Any help would be greatly appreciated.
