I did exactly as you suggested, but reported this error:
** Error: Line 60: Output argument "varargout{2}" (and maybe others) not assigned during call to "cat_system".
**
** Call stack:
** >cat_surf_map_atlas.m at 60
** >process_segment_cat12.m>Compute at 382
** >process_segment_cat12.m>ComputeInteractive at 445
** >process_segment_cat12.m at 28
** >bst_call.m at 28
** >tree_callbacks.m>@(h,ev)bst_call(@process_segment_cat12,'ComputeInteractive',iSubject,iAnatomy) at 3005
**
Do you have any suggestions?
Thank you very much for your help!
