I am experiencing a problem with loading a MAT-file in CONN during the setup process. The specific error occurs at the step where ROI data is being imported.

Error Details:

• CONN Version: CONN22.a


• SPM Version: SPM12


• MATLAB Version: MATLAB v.2020a


• Error Description:

Error using load
Unable to read MAT-file /Volumes/My Passport/conn_project01/data/ROI_Subject103_Session001.mat. File might be corrupt.

Error in conn_process (line 853)
 old=load(filename);%,'data','names','source','xyz','sampledata','samplexyz');

Error in conn_process (line 55)
 case 'setup', conn_disp(['CONN: RUNNING SETUP STEP']); conn_process([0:4,4.5,5]);

Error in conn (line 6392)
 conn_process(processname); ispending=false;

Error in conn_menumanager (line 124)
 feval(CONN_MM.MENU{n0}.callback{n1}{1},CONN_MM.MENU{n0}.callback{n1}{2:end});

Could you please advise on how to proceed with this issue? Is there a way to repair or recover the file, or should I attempt to regenerate the file? Any guidance or suggestions would be greatly appreciated.

Thank you, Rasha
