RePosting : Horzcat error

Didn't get a reply so re-posting the below message. It is now happening for multiple data sets so I would be very grateful for some suggestions... ....................................... Hello, Having an error listed below when trying to do seed based resting FC. I ran the same options and used the same ROIs with another data set and had no errors so don't think it is my choice of ROIs. I am running DPARSF_V2.1_120101, SPM8, Matlab R2011b. ============ Error using horzcat CAT arguments dimensions are not consistent. Error in DPARSFA_run (line 1924) Covariables=[Covariables,theROITimeCourses]; Error in DPARSFA>pushbuttonRun_Callback (line 1133) [Error]=DPARSFA_run(handles.Cfg); Error in gui_mainfcn (line 96) feval(varargin{:}); Error in DPARSFA (line 31) gui_mainfcn(gui_State, varargin{:}); Error while evaluating uicontrol Callback ======================== This happened just after my last subject finished with this job : "Extracting ROI timecourses over..." and no FC folders are created in FunImg or in the Results folder. Thank you, in advance, for your suggestions- Desmond
