Dear Lillian,
The best advice, as stated by James, would be to re-analyse your data
with SPM12. There has been so many changes and improvements since SPM2
that it is definitely worth the effort.
Using the SPM2 version from the GitHub repository mentioned by James, I
could specify and estimate a GLM using MATLAB R2010a, so this is an
option for you if you just want to review results that were found long
time ago with SPM2.
Out of curiosity, I opened the SPM2 results I just obtained in SPM12 and
got the same error than you. If you make a backup of the SPM.mat file
and then run the following:
load SPM.mat
SPM.Vbeta = spm_vol(strvcat(SPM.Vbeta.fname));
SPM.VResMS = spm_vol(SPM.VResMS.fname);
SPM.VM = spm_vol(SPM.VM.fname);
for i=1:numel(SPM.xCon)
if ~isempty(SPM.xCon(i).Vspm)
SPM.xCon(i).Vcon = spm_vol(SPM.xCon(i).Vcon.fname);
SPM.xCon(i).Vspm = spm_vol(SPM.xCon(i).Vspm.fname);
end
end
save SPM.mat SPM -v6
you should be able to review the results again. There might be a number
of very good reasons why you might observe slightly different values
compared with SPM2.
Best regards,
Guillaume.
