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-
