Hi all!
I tryed to run an Ancova with SPM99, but it failed. I've got two groups
(men (n=22) and women (n=22)) in which there are 11 good performers and 11
bad performers in each group. In this analysis the performance is my
covariate. I entered all contrast image of the two groups of subjects (Men
and Women) and then the vectors of the covariate (42): 1 1 1 1 1 1 1 1 1 1
1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 .... and so on. I choose "no grand mean
scaling", thresold masking: none, explicity mask image no and omit. Then
I've got this error message:Mapping files : ...done
Design configuration : ...done
Saving SPMstats configuration : ...SPMcfg.mat saved
Design reporting : ??? Error using ==> <

Error in ==> c:\spm99\spm_DesMtx.m

Error in ==> c:\spm99\spm_spm_ui.m
On line 1416 ==> spm_DesRep('DesMtx',xX,reshape({VY.fname},size(VY)),xsDes)
??? Error while evaluating uicontrol Callback.
Please could you help me to well made this ancova. Thank you.
Best regards
